Pgx copyfrom github Wrap or ocsql. Because the panic still causes defers to happen, the defer goes off, but pbr was never set with a return, so pbr. DB) and I wonder if I can execute any pgx code using it. COPY cannot be used with prepared statements, and Currently CopyFromRows is rather cumbersome to use and similarly implementing a custom type is often annoying. For our code we need to able to use the table name in a case insensitive way. PgConn). Below is the code that I used to construct Timestamptz struct: timeVal := pgtype. Row). PostgreSQL driver and toolkit for Go. Conn when needed. Query because I want to get the returning id from the result row. Actual behavior PostgreSQL error: ERROR: invalid address family in external "inet" value (SQLSTATE 22P03) Version. The text was updated successfully, but If you identify internal Postgres APIs you need, open an issue and we'll get them exposed, at least through the pgx::pg_sys module. @jackc @pashagolub appreciate the responses, they make sense. Adding pgx = { version = "0. pgx is a pure Go driver and toolkit for PostgreSQL. However, the COPY protocol requires all values to be encoded in the same format. Conn has a large interface. Checklist. Working code: ` var rows [][]any Nothing jumps out at me.

CopyFrom to copy files like with \copy in the psql CLI tool. In the During debugging I have found that one of my go-routines got sutck on pgx. The problem is that this function takes an iterator interface to pull data into itself, which is rather awkward if the caller is fundamentally copyfrom. I think you should accumulate your rows, figure out their types, then pass those as the [][]interface{} like the method expects. Even a short read deadline waiting to do nothing can have a significant negative performance impact in certain circumstances such as CopyFrom (see #1481). Reset() inside. Row's Scan will return ErrNoRows. expectations. A particular call to a *pgxpool. CopyFromSource) (int64, error) Now copyfrom can't support data types such as box, bit ,etc. However, the two pools didn't work together very well. Row's Scan method is called. Upon reading 'null' value decodes to nil, which then can't be written back as it encodes to NULL. Since I'm not registering the types, and the tests pass in If this is in fact a pgx issue I'm having, I'll gladly add more supporting information upon Pgx is intended to complement these JAX-native environments with (classic) board game suits:. I do not think this is a bug. It also includes an adapter for the standard database/sql interface. I think the cause of problem is parseDriver function ne PostgreSQL driver and toolkit for Go. pgx's CopyFrom only supports the binary format. output_copyfrom_file_name: Customize the name of the copyfrom file. conn is nil. What database engines are you using? PostgreSQL. 5. It would be ideal if there was an option (LOG_VERBOSITY) to show which lines with which errors could not be inserted for output t Contribute to ZGeomantic/pgx development by creating an account on GitHub. You can use pgconn. CopyFrom is a higher level function that runs through the pgx type system. IPNet to and from inet and cidr PostgreSQL types. Identifier like so: copyCount, err := dstConn. The type of the bound variable will also be a double precision as that is what it is being compared to. Query to conn. Conn wrapper instead (for advanced pgx functionalities such as CopyFrom) I do think that this should not be done as part of this repo as this In v3 of pgx OpenDBFromPool was used to allow the database/sql and pgx pools to co-exist. I'm writing "yet another specialized smart data migrator" for project needs, and got stuck at jsonb. with JSON handling. Is there an alternative way to do this? Thank you! I am sorry if my question is silly. read tcp 172. Contribute to jackc/pgx-top-to-bottom development by creating an account on GitHub. Numeric on interfaces values broken Describe the bug We're seeing an issue wherein we can consistently reproduce application hangs with pgx/v5 that do not occur with pgx/v4. It remains as similar to the database/sql interface as possible while providing better speed and access to The CopyFrom function is available to a pgx connection and it utilizes PostgreSQL’s native copy functionality. Conn(). This is correct behavior. OpenDB but I guess everyone would benefit from a native pgx. A quick solution is to add overrides For Postgresql 17: I would like to be able to run the CopyFrom function with the ON_ERROR ignore parameter. . (c * Conn) CopyFrom (ctx context. CopyFrom(ctx, pgx. Unfortunately, I have not found a description / example of how I can link this adapt As above really. Conn object but I don't see a way to call CopyFrom via sql. A variadic options argument could be added CopyFrom. ReleaseConn(s. While this works, it is a somewhat annoying to have to drop down from sqlx. DB. PgConn? e. It could be, but will require a bit of work with cargo-pgx and figuring out how to compile pgx's "cshim" static library. With timestamptz the time zone is always UTC. I have encountered this problem too. The problem is, we're opening the DB connection using the stdlib compat db, err := sql. Add tests covering new code. pgx takes advantage of this with CopyFrom and uses the binary format. But it would be sub-optimal to make the user do that work, but I guess it's better than not having the feature at all. Since your data is already formatted in CSV it might be simpler just to use the lower level pgconn function. CopyFrom - cannot convert -infinity to Timestamptz Hi @jackc , I'm trying to copy a set of values from a source table with column type timestamp with time zone default '-infinity'::timestamp with time zone using the https://pkg. AcquireConn(s. Type that supports the binary format must be registered for the type of each column. When pgx detects your underlying data is a string it simply passes it to PostgreSQL as-is. But you can use sqlx with pgx when pgx is used as a database/sql driver. The only changes to the application itself between the pgx/v4-based version that works and the pgx/v5 version that doesn't are those necessitated by the API differences between the two versions (namely, Tracing do work if you use stdlib. com/jackc/pgx/v5/pgconn" ) // CopyFromRows returns a CopyFromSource interface PostgreSQL driver and toolkit for Go. dev/github. Expected behavior The data should load OK. It will connect to the database specified in the PGX_TEST_CONN_STRING environment variable. This is the previous stable v4 release. 0 What happened? #2545 introduced a :copyfrom feature for MySQL database thanks to @kyleconroy . package pgx import ( "bytes" "context" "fmt" "io" "github. Sign up for GitHub By clicking The new CopyFrom method uses this Identifier type. Conn by AcquireConn() in order to Hello, I'm sure this have been brought up numerous, numerous times as it's quite an issue with how Go traditionally deals with NULL values as opposed to how it traditionally deals with zeroed values, and you don't need to have a 10-year perspective on Go like some of us do— to see that there's impediment to ergonomics, as well as memory allocation patterns whenever This is more a question. The driver component of pgx can be used alongside the standard database/sql package. Once they start, they never stop until I restart the app. What happened? When using named parameters in your insert statement (@param_name or sqlc. Try to isolate this example to a reproduction case that doesn't require Mongo. GitHub community articles Repositories. Contribute to efectn/go-orm-benchmarks development by creating an account on GitHub. Now I want to switch to version v5. CopyFrom: func (c *Conn) CopyFrom(tableName Identifier, columnNames []string, rowSrc CopyFromSource) (int, error) CopyFrom uses the PostgreSQL copy protocol to perform bulk data insertion. 4:44010->172. copyIn("COPY my_table FROM STDIN FORMAT csv", Greetings! I am able to reliably reproduce a crash when Close()-ing an exhausted pgx. It is built on top of pgconn. CopyFromSource) (int64, error) {return tx. CopyTo is The problem is unmarshalling the literal JSON string "foo" into a Go string removes the quotation marks. When doing an insert, one can simply specify on conflict do nothing to ignore unique constraint violations. Cheers ️ We need to implement tracing (via pgx) to debug connection issues but cannot use the pgx interface because entgo requires a *sql. 0) for the COPY method and got an interesting behavior: the code on my local system with Postgres 14. It seems Query with INSERT RETURNING is not working well. example usage of Copy: {"John", "Smith", pgx. Table has jsonb not null field. The toolkit component is a related set of packages that In the code above, SendPrepare() panics, because pipeline. Conn. First, CopyFrom isn't supported from stdlib but you can use stdlib. // TraceCopyFromStart is called at the beginning of CopyFrom calls. pgx aims to be low-level, fast, and performant, while also enabling PostgreSQL-specific features that the standard database/sql package does not allow for. Usually the values people want to insert are in a slice, so a helper for such situation would be neat. go at master · pashagolub/pgxmock You signed in with another tab or window. To compromise, I ended up COPYing the records into a separate staging table and then doing validation/constraint checking against the parent table in a separate process. The reason for this problem is neither google/uuid nor gofrs/uuid implements the BinaryEncoder interface which needs by the pgx to encode your data during COPY. pgx is different from other drivers such as pq because, while it can operate as a database/sql compatible driver, pgx is also usable directly. Right now CopyFrom requires a Prepare and as far as I could tell this is just used to get type information. Query to tx. When encoding a string to a PostgreSQL json type, pgx assumes that it is an encoded JSON document, not a literal string that should be encoded into a JSON value. t. Exec and then queried another select to get the id, then problem was solved!. pgx requires the Go types to exactly match the PostgreSQL types (with a few limited exceptions). 1: If i attempt to insert large amounts of data, say 1,000 rows, only 957 will actually make it to the database. OnNotification. See the PostgreSQL driver and toolkit for Go. CopyFromRows(rows))` ERROR: invalid address family in external "inet" value (SQLSTATE 22P03) My code works well for basic types such as string or integers, so I wonder if this is a bug or a feature request. Identifier, columnNames [] string, rowSrc pgx. Create a table with an inet column. pgx v4 is less complicated than v3 because of this separation of concerns. Is it possible? If so is there some example of how to do it? with tx. It offers a native interface similar to database/sql that offers better performance and more features. pgx is different from other drivers such as pq because, while it can operate as a database/sql compatible driver, pgx is pgx is a pure Go driver and toolkit for PostgreSQL. To Reproduce Wrote a simple program to demonstrate: package ma Contribute to jackc/pgx development by creating an account on GitHub. The current interface from CopyFrom makes it hard to copy from a map and especially sync. Connect throw hundreds of busy connection messages and all concurrent queries, ajax services and API broken; scan float64 is not possible, and forcing the float64 to scan pgx. Rows. CopyFrom() in my code to execute copy commands and send data to server. DB) if err != nil { return err } defer stdlib. In v4, OpenDBFromPool was removed.

What library should I use? Kotlin example for reference: val cm = CopyManager(conn as BaseConnection) val total = cm. I now modified the program to still use my csvsource to provide and convert the values but changed the CopyFrom not to use the source directly but use pgx. pool. If the query selects no rows, pgx. If you really want to pass in a Go int64 to compare with a PostgreSQL double Hello, i have migrated our application from pq to pgx pretty much successfully but I still cannot solve one issue, when calling (simplified) arg := []string{"test"} db. Describe the bug When using CopyFrom in V4 you could use string values for column fields of type enum. The PGX_TEST_CONN_STRING environment variable can be a URL or DSN. If so I add them to an INSERT . BinaryEncoder: missing method EncodeBinary The p Hello, First of all, thank you a lot for pgx which is very robust and works incredibly well in our codebase! I am using the CopyFrom feature to load data into a table, and I need to insert a NaN. – pgx - PostgreSQL Driver and Toolkit. I'd really love to have sqlc generate type-safe CopyFrom methods, as CopyFrom is orders of magnitude faster than sequential inserts. If you send a null schema into pgx. // Desired Behaviour Support direct pgx calls Additional context We PostgreSQL driver and toolkit for Go. Identifier{"", "dstTable"}, columnNames, pgx. I am qu As of v5. Before this type ExpectedReset should be defined the same way as for example ExpectedClose. PgConn(). 3, when there is no way to encode a value in binary format, but there is a way to encode it in text format (for example [][]string into a numeric[], CopyFrom will encode the value into the text format, then parse it, then reencode it into the binary format. pgx - PostgreSQL Driver and Toolkit. 0", features = ["postgrestd"] } to your Cargo. go; Define a new type ExpectedReset that embeds the commonExpectation struct. These didn't quite line up, but since Gorm V2 uses pgx, I think I can close this out. AcquireConn get a native *pgx. It returns the number of rows copied In most cases the binary format is much faster. Everything works fine, unless I try to write any of these column types: geography, Saved searches Use saved searches to filter your results more quickly pgx is a pure Go driver and toolkit for PostgreSQL. go shown below seems to be generated improperly. It looks like you're basically still doing a single-row insert. The workaround I'm using to still insert many vectors at once is the :batchexec command, which works fine Version. @jackc - the issue here is that we maintain a Gorm instance instead of a connection object, so we were only able to access functionality to database/sql through interfaces that Gorm provided. Hello, We are inserting large amounts of records at once into a very flat table and pgx reports a Connection close issue. Rather than pgx wrap every low level function of Hello, I've just started using your library, pretty impressed, esp. toml will enable a highly experimental variant of pgx designed for integration with postgrestd, a modified Rust standard library that executes the Rust runtime atop the Postgres runtime, instead of using the operating system's ordinary C runtime. CopyFrom to copy data from pgx. Using a cache would work as well. PyPGx is and always will be completely free and open source. Exec and conn. For debugging purposes I also enabled message tracing provided by pgproto3. Windows is not supported. As far as using pgx specific functionality such as CopyFrom, I'm not sure if it is possible. I could not find any working example of how to test CopyFrom command using pgxmock. DB to pgx. D The binary format of both timestamp and timestamptz is a 64-bit integer of the number of microseconds since 2000-01-01 00:00:00. Because we know the time zone it JSON and JSONB Mapping pgx includes built-in support to marshal and unmarshal between Go types and the PostgreSQL JSON and JSONB. Null} timeVal. I have not yet dug into isolating it into a standalone test - it is relatively difficult given the complexity of the codepath. CopyFrom() I don't think it is possible to handle all cases, and even what could be handled beyond Query, QueryRow, and Exec could have significant complexity. It returns the number of rows copied and an error. 1. conn. CopyFrom which correctly passes field types? Hello I need to do a bulk insert of thousands of rows using the copy protocol. 6. To always emit a parameter struct, set this to 0. My intention in v4 is that pgx handles high level interactions with PostgreSQL and pgconn handles low level interactions with PostgreSQL. Go: 1. This would avoid adding a new function or breaking compatibility. It already tried to parse strings to values that can then be encoded into the binary format. The toolkit component is a related set of packages that implement PostgreSQL sqlx requires database/sql so you will have to use the pgx/v5/stdlib package. Select(&data, ` SELECT a. However, this means if you are using CopyFrom uses the PostgreSQL copy protocol to perform bulk data insertion. ResultReader expected statement description, got *pgconn. You switched accounts on another tab or window. Tx Did not realize that Timestamptz is defined as a struct in pgx. Greetings, I have been having issues with pgx CopyFrom to do bulk inserts. Topics Trending but the code pertains to registering types with pgx in a situation where the user needs to use CopyFrom. It could work similarly Advanced benchmarks for +15 Go ORMs. The pgx driver is a low-level, high performance interface that exposes PostgreSQL-specific features such as LISTEN / pgx provides lower level access to PostgreSQL than the standard database/sql. Pool for my web apps. Defaults to copyfrom. Have a question about this project? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Rows retrieved from a query into a target table. However because CopyFrom uses Identifier it always adds quote to the table name, e. DB object,. query_parameter_limit: The number of positional arguments that will be generated for Go functions. Identifier, columnNames []string, rowSrc pgx. QueryRow acquires a connection and executes a query that is expected to return at most one row (pgx. ". 22. However, it falls back to simulating non-blocking I/O by using short deadlines on Windows. Notifications You must be signed in to change notification New issue Have a question about this project? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. A quick solution is to add overrides PostgreSQL driver and toolkit for Go. I'd like to use one connection of a pool for having a LISTEN open, if that connection dies another one should run the LISTEN reverting back to pgx. When I tried copying into a [PART 1] pgx v5 support (#1823) #1873 - To support two version of pgx in the e2e tests at the same time we move 'pgx/v4' tests to the separated v4 directory. v5 been released. pool safe against deadlocks ???. Then new 'pgx/v5' e2e tests will be located in the v5 dir. The main purpose of the PyPGx package is to provide a unified platform for pharmacogenomics (PGx) research. Summary Per nrpgx. I was wondering if there's anything I can do to achieve the same behavior while utilizing the much faster CopyFrom protocol. I'm imagining sqlc could detect simple insert statements like INSERT INTO table (a, b, c) VALUES ($1, $2 From the pgx docs, use pgx. output_files_suffix: If specified the suffix will be added to the name of the generated files. Somewhat hackey, but the speed benefits from COPY were too good to pass up. A pgtype. I changed this tx. Saved searches Use saved searches to filter your results more quickly Host and manage packages Security. The pgx driver is a low-level, high performance interface that exposes PostgreSQL-specific features such as LISTEN / NOTIFY and COPY. PipelineSync unexpected pipeline result: *pgco 2) CopyFrom is for copying rows (plural): "CopyFrom can be faster than an insert with as few as 5 rows. 2: If i attempt to use CopyFrom to insert less th jackc / pgx Public. My impression is that there is really something wrong in using CopyFrom with the source directly. GenericText is not pgtype. Add logging on CopyFrom (Patrick Hemmer) Add comment support when sanitizing SQL queries (Rusakow Andrew) Do not panic on double close of pgxpool. You should be able to use ocsql. pgx wouldn't know to handle a runtime created type (or rather it would treat it as generic text). PostgreSQL: 12, pgx: latest The postgres I have an application which imports data in multiple stages using big INSERT statements, and I'm about to rewrite it to use CopyFrom() so that the data can be streamed directly to Postgres with minimal buffering of the row data. For example, what if the first thing done in the transaction was something on the underlying pgconn. The thing is, I have multiple go-routines using single pool. I'm seeing spurious conn busy errors on my development machine. Hello 👋 I am just wondering how to use CopyFrom on a file. nullstring or string, but CopyFrom depends on the pgx types, it's difficult to use this powerful feature, because must convert the sql data to pgx types before using it, but postgresql's types are too many to convert and may bring new data types Saved searches Use saved searches to filter your results more quickly pgx. In addition, the standard PG* environment variables will be respected. I've been working for the last couple of weeks with postgres and found this amazing library for which I thank you! While writing my tests I've encountered a scenario where I would like to pass complete sql files generated by the pg_dump Describe the bug Turns out it's a minor thing but tripped me up for a bit. ON CONFLICT batch, otherwise I use CopyFrom. The app uses pgx basically I'm using https://pkg. CopyFrom(ctx context. Timestamptz{Status: pgtype. Not sure how that would interact with the testing libraries you are using though. But it is nice to write some documents to warn people who want to COPY UUID type. Ordinarily, you could use db. CopyFrom(ctx, tableName, columnNames, rowSrc)} // SendBatch delegates to the underlying *Conn. I am using the pool with CopyFrom and Exec, so, Acquire should release any resouces if those were allocated and free the connection. Pool (Matt Schultz) PostgreSQL driver and toolkit for Go. Conn from stdlib and do the CopyFrom with that. It might not I want to use LISTEN together with pgxpool. is these new data types in plan to support ? @jackc Hi. This may reduce the need for this feature. 0. Pool method may block, but it is safe to call into it concurrently from multiple goroutines. Frontend. I use (*pgconn. CopyFrom(ctx, tableName, columnNames, rowSrc)} The pgconn tests require a PostgreSQL database. For this version there is also an adapter for the Zap Logger. The returned context is used for the Saved searches Use saved searches to filter your results more quickly Contribute to jackc/pgx development by creating an account on GitHub. Conn is not concurrency safe and *pgxpool. CopyFrom which is basically just a pipe to copy data. @kynetiv - tbh, replacing pgx with pq worked completely fine except for the copy in From a pgx point of view what you are proposing will work. This behaviour is broken in V5. Raw call will only produce pgx. Conn or Tx object from the sql. Query, it looks like it is using a query argument. DB connection we have already built all the system around? I have encountered this problem too. CopyFromSource input. go. pgx uses non-blocking I/O on *nix. We're currently in the progress of moving from lib/pq to pgx and we're hitting a problem with CopyFrom. RegisterConnConfig to configure any pgx settings that can't be set through the connection string. CopyFromRows(filte First, thanks for this suite of tools and giving of your time/knowledge :) I'm kind of struggling to upgrade to v5, and it may just be due to how we're using pgx. Map Sign up for a free GitHub account to open an issue and contact its maintainers maybe it would make sense to come up with efficient implementations for these which could be part of pgx. The second is to write your application in terms of interfaces instead of structs. You signed in with another tab or window. So, the question is, is pgx. x FROM table_a a LEFT JOIN LATERAL ( SE As you say, there are several places to find the binary format (and pgx already implements most types in binary). In addition, as a convenience pgx will encode from a net. [PART 2] pgx v5 support (#1823) #1874 - support pgx v5 in the sqlc [PART 3] pgx v5 support (#1823) #1875 - added e2e tests for pgx v5 There are a few possibly intersecting issues here. Perhaps manually construct the slice to pass to CopyFrom that demonstrates the problem. dev/g pgx internally creates a prepared statement for all queries that have result sets. The fulfilled() method should QueryRow acquires a connection and executes a query that is expected to return at most one row (pgx. tx. The driver component of pgx can be used alongside the standard Saved searches Use saved searches to filter your results more quickly You signed in with another tab or window. Opening this ticket The function should use pgxmock. I was just reading the pgx CopyFrom code, seems to me CopyTo would be exactly the reserve as you said. CopyFrom uses the PostgreSQL copy protocol to perform bulk data insertion. Tx supports CopyFrom but there seems to be no way to use it from sql driver. I'm thinking the defer might change to the following to prevent the "panic hiding" that I It would be more correct to say that *pgx. I do not have a Windows dev box nor do I have the Windows expertise to easily pgx does not have anything like sqlx. A clear and You signed in with another tab or window. I noticed that there is a CopyFromReader in v3, but there doesn't seem to be in v4. To make sure I understand what you suggested, by "without parsing the results", you mean to iterate through with rows. 2; pgx Hello, I'm trying to insert some struct, the one I have is this one : type Card struct { ID int Level int Info string Tasks [2]string Achievements []string Dungeons [3]string Spell string } It cont I read #287, could it be it broke something with enum handling? I get a panic when trying to insert a custom type (with string being the underlying type): *pgtype. Describe alternatives you've considered Before adding them to CopyFromRows, I am currently inspecting records and determining if they could cause a violation. Open("pgx", "") which returns a generic sql. Even though enum types appear to be strings they still must be registered to use with CopyFrom. Conn. Now I changed the library to PGX (jackc/pgx/v5 v5. Hi, I'm trying to use the CopyFrom function to duplicate the data from some tables, using the result from a SELECT query as the pgx. However, I prefer the pool creation to be directly called rather than rely on package init(). However, it is not woking well. Err causes another nil pointer dereference inside the defer statement and hides the first panic. *, y. Is there a way to get a pgx. pgx has WaitForNotification() and pgconn has Config. Close()? To dump a snapshot of a table, I would just use SELECT There's a few possibilities to do what you want. Attempt to load data using CopyFrom and provide a string variable with just an IP address as the data. In the last example with Copy(tx). Inet and CIDR Mapping pgx encodes from net. My setup is that I use pgx/stdlib Saved searches Use saved searches to filter your results more quickly Thanks Jack. What type of code are you generating? Go. But after this query, all prepare statements fail. Register along with pgx's stdlib. Almost all types implemented by pgx support the binary format. But it would probably be simpler to use database/sql and acquire a pgx connection from it when you need PostgreSQL functionality such as COPY FROM. Otherwise, pgx. pgx mock driver for golang to test database interactions - pgxmock/pgxmock. • Implement the expectation interface for the ExpectedReset type. According to pgx documentation CopyFrom requires all values use the binary format. CopyFromRows. A new function could take a options struct. Just using $4 for updated_by and inputting same value twice in CreateAuthors solves the problem for now, but I hope this kind of awkwardness will be reduced. return tx. go, it states: // USING WITH DIRECT PGX CALLS WITHOUT DATABASE/SQL // // This mode of operation is not supported by the nrpgx integration at this time. But I am seening that on But a pgx. Next() without scan, and then rows. Row's Scan scans the first selected row and discards the rest. I will do a benchmarking. IP; it will assume a /32 netmask for IPv4 and a /128 for IPv6. Reading or writing a raw stream of data through the copy protocol seemed to be a low level action. Set(theTime) Build Postgres Extensions with Rust! Contribute to postgresml/pgx development by creating an account on GitHub. Context, tableName pgx. 12 worked as it should and inserted all my data fine. AcquireConn() to get a *pgx. com/jackc/pgx/v5/internal/pgio" "github. Is there some generalized method to pass data from conn. I usually have a single *pgxpool. Ideally I would customize the ON CONFLICT (xxx) DO yyy; part through pgx.

This is also correct behavior. Defaults Hey. There's nothing preventing you from establishing native pgx pools or connections at the same time as database/sql. 20. At its core, sqlc is powered by SQL engines, which include parsers, formatters, analyzers and more. It remains as similar to the database/sql interface as possible while providing better speed and pgx provides lower level access to PostgreSQL than the standard database/sql. What's New Remote code generation. This does now work and does NOT drop lines. Describe the bug It's not clear what happened but we had a bunch of the following errors: expected statement description, got *pgconn. Describe the solution you'd like I think the default CopyFrom interface should stay as-is but I would like an alternative "Power User" API that allows me to avoid the Prepare on every call to CopyFrom. Version 1. Contribute to joel113/forked-pgx development by creating an account on GitHub. Hi, I use the v4 version together with the Zap Logger. g. CopyIn() is very easily and faster, it doesn't depend on the pgx or sql types in most cases, just put sql. This functionality can be accessed now at the pgconn layer, but it's not clear what would be the best interface would be at the pgx level. First of all, thank you for this package. Thanks for the great helper for pgx. What operating system are you using? Linux. Instead use database/sql as the connection pool and use db. 18. AcquireConn to get a pgx pgx. Raw() or stdlib. First, pgx reads on the PostgreSQL type catalog when it first connects and builds a translation table of OID (type ID number) to conversion routine. arg(param_name)) the parameter name is used in the pgx CopyFrom method instead of the column name. You signed out in another tab or window. Pool is concurrency safe. 👍 10 rfloriano, ar3s3ru, aitchwhy, IshanDaga, darylhjd, sixilli, anhnmt, evgio, melekhine, and kelevro reacted with thumbs up emoji hi @jackc Use pq. Workaround. pgx works beautifully after putting the right encoding for CopyFrom. Reload to refresh your session. Developed by @andrewmbenton. Errors are deferred until pgx.
