# 5.5.5 (March 9, 2024)
|
|
|
|
Use spaces instead of parentheses for SQL sanitization.
|
|
|
|
This still solves the problem of negative numbers creating a line comment, but this avoids breaking edge cases such as
|
|
`set foo to $1` where the substitution is taking place in a location where an arbitrary expression is not allowed.
|
|
|
|
# 5.5.4 (March 4, 2024)
|
|
|
|
Fix CVE-2024-27304
|
|
|
|
SQL injection can occur if an attacker can cause a single query or bind message to exceed 4 GB in size. An integer
|
|
overflow in the calculated message size can cause the one large message to be sent as multiple messages under the
|
|
attacker's control.
|
|
|
|
Thanks to Paul Gerste for reporting this issue.

|
|
|
|
* Add CopyFromFunc helper function. (robford)
|
|
* Add PgConn.Deallocate method that uses PostgreSQL protocol Close message.
|
|
* pgx uses new PgConn.Deallocate method. This allows deallocating statements to work in a failed transaction. This fixes a case where the prepared statement map could become invalid.
|
|
* Fix: Prefer driver.Valuer over json.Marshaler for json fields. (Jacopo)
|
|
* Fix: simple protocol SQL sanitizer previously panicked if an invalid $0 placeholder was used. This now returns an error instead. (maksymnevajdev)

|
# 5.5.0 (November 4, 2023)
|
|
|
|
* Add CollectExactlyOneRow. (Julien GOTTELAND)
|
|
* Add OpenDBFromPool to create *database/sql.DB from *pgxpool.Pool. (Lev Zakharov)
|
|
* Prepare can automatically choose statement name based on sql. This makes it easier to explicitly manage prepared statements.
|

|
|
* database/sql prepared statement names are deterministically generated.
|
|
* Fix: SendBatch wasn't respecting context cancellation.
|
|
* Fix: Timeout error from pipeline is now normalized.
|
|
* Fix: database/sql encoding json.RawMessage to []byte.

|
* Fix: QCharArrayOID was defined with the wrong OID (Christoph Engelbert)
|
|
* Fix: connect_timeout for sslmode=allow|prefer (smaher-edb)
|
|
* Fix: pgxpool: background health check cannot overflow pool
|
|
* Fix: Check for nil in defer when sending batch (recover properly from panic)
|
|
* Fix: json scan of non-string pointer to pointer
|
|
* Fix: zeronull.Timestamptz should use pgtype.Timestamptz
|
|
* Fix: NewConnsCount was not correctly counting connections created by Acquire directly. (James Hartig)
|
|
* RowTo(AddrOf)StructByPos ignores fields with "-" db tag
|
|
* Optimization: improve text format numeric parsing (horpto)
|
|
|
|
# 5.4.2 (July 11, 2023)
|
|
|
|
* Fix: RowScanner errors are fatal to Rows
|
|
* Fix: Enable failover efforts when pg_hba.conf disallows non-ssl connections (Brandon Kauffman)
|
|
* Hstore text codec internal improvements (Evan Jones)
|
|
* Fix: Stop timers for background reader when not in use. Fixes memory leak when closing connections (Adrian-Stefan Mares)
|
|
* Fix: Stop background reader as soon as possible.
|
|
* Add PgConn.SyncConn(). This combined with the above fix makes it safe to directly use the underlying net.Conn.
|
|
|
|
# 5.4.1 (June 18, 2023)
|
|
|
|
* Fix: concurrency bug with pgtypeDefaultMap and simple protocol (Lev Zakharov)
|
|
* Add TxOptions.BeginQuery to allow overriding the default BEGIN query
|
|
|
|
# 5.4.0 (June 14, 2023)
|
|
|
|
* Replace platform specific syscalls for non-blocking IO with more traditional goroutines and deadlines. This returns to the v4 approach with some additional improvements and fixes. This restores the ability to use a pgx.Conn over an ssh.Conn as well as other non-TCP or Unix socket connections. In addition, it is a significantly simpler implementation that is less likely to have cross platform issues.
|
|
* Optimization: The default type registrations are now shared among all connections. This saves about 100KB of memory per connection. `pgtype.Type` and `pgtype.Codec` values are now required to be immutable after registration. This was already necessary in most cases but wasn't documented until now. (Lev Zakharov)
|
|
* Fix: Ensure pgxpool.Pool.QueryRow.Scan releases connection on panic
|
|
* CancelRequest: don't try to read the reply (Nicola Murino)
|
|
* Fix: correctly handle bool type aliases (Wichert Akkerman)
|
|
* Fix: pgconn.CancelRequest: Fix unix sockets: don't use RemoteAddr()
|
|
* Fix: pgx.Conn memory leak with prepared statement caching (Evan Jones)
|
|
* Add BeforeClose to pgxpool.Pool (Evan Cordell)
|
|
* Fix: various hstore fixes and optimizations (Evan Jones)
|
|
* Fix: RowToStructByPos with embedded unexported struct
|
|
* Support different bool string representations (Lev Zakharov)
|
|
* Fix: error when using BatchResults.Exec on a select that returns an error after some rows.
|
|
* Fix: pipelineBatchResults.Exec() not returning error from ResultReader
|
|
* Fix: pipeline batch results not closing pipeline when error occurs while reading directly from results instead of using
|
|
a callback.
|
|
* Fix: scanning a table type into a struct
|
|
* Fix: scan array of record to pointer to slice of struct
|
|
* Fix: handle null for json (Cemre Mengu)
|
|
* Batch Query callback is called even when there is an error
|
|
* Add RowTo(AddrOf)StructByNameLax (Audi P. Risa P)
|
|
|
|

|
|

|
|
* Fix: LoadType for composite with dropped attributes (Felix Röhrich)
|
|

|
|
|
|
# 5.2.0 (December 5, 2022)
|
|
|
|
* `tracelog.TraceLog` implements the pgx.PrepareTracer interface. (Vitalii Solodilov)
|
|
* Optimize creating begin transaction SQL string (Petr Evdokimov and ksco)
|
|
* `Conn.LoadType` supports range and multirange types (Vitalii Solodilov)
|
|
* Fix scan `uint` and `uint64` `ScanNumeric`. This resolves a PostgreSQL `numeric` being incorrectly scanned into `uint` and `uint64`.
|
|
|
|
# 5.1.1 (November 17, 2022)
|
|
|
|
* Fix simple query sanitizer where query text contains a Unicode replacement character.
|
|
* Remove erroneous `name` argument from `DeallocateAll()`. Technically, this is a breaking change, but given that method was only added 5 days ago this change was accepted. (Bodo Kaiser)
|
|
|
|
# 5.1.0 (November 12, 2022)
|
|
|
|
* Update puddle to v2.1.2. This resolves a race condition and a deadlock in pgxpool.
|
|
* `QueryRewriter.RewriteQuery` now returns an error. Technically, this is a breaking change for any external implementers, but given the minimal likelihood that there are actually any external implementers this change was accepted.
|
|
* Expose `GetSSLPassword` support to pgx.
|
|
* Fix encode `ErrorResponse` unknown field handling. This would only affect pgproto3 being used directly as a proxy with a non-PostgreSQL server that included additional error fields.
|
|
* Fix date text format encoding with 5 digit years.
|
|
* Fix date values passed to a `sql.Scanner` as `string` instead of `time.Time`.
|
|
* DateCodec.DecodeValue can return `pgtype.InfinityModifier` instead of `string` for infinite values. This now matches the behavior of the timestamp types.
|
|
* Add domain type support to `Conn.LoadType()`.
|
|
* Add `RowToStructByName` and `RowToAddrOfStructByName`. (Pavlo Golub)
|
|
* Add `Conn.DeallocateAll()` to clear all prepared statements including the statement cache. (Bodo Kaiser)
|
|
|
|
# 5.0.4 (October 24, 2022)
|
|
|
|
* Fix: CollectOneRow prefers PostgreSQL error over pgx.ErrorNoRows
|
|
* Fix: some reflect Kind checks to first check for nil
|
|

|
|
|
|
# 5.0.3 (October 14, 2022)
|
|
|

|
|
|
|

|
# v5.0.0 (September 17, 2022)
|
|
|
|
## Merged Packages
|
|
|
|
`github.com/jackc/pgtype`, `github.com/jackc/pgconn`, and `github.com/jackc/pgproto3` are now included in the main
|
|
`github.com/jackc/pgx` repository. Previously there was confusion as to where issues should be reported, additional
|
|
release work due to releasing multiple packages, and less clear changelogs.
|
|
|
|
## pgconn
|
|
|
|
`CommandTag` is now an opaque type instead of directly exposing an underlying `[]byte`.
|
|
|
|
The return value `ResultReader.Values()` is no longer safe to retain a reference to after a subsequent call to `NextRow()` or `Close()`.
|
|
|
|
`Trace()` method adds low level message tracing similar to the `PQtrace` function in `libpq`.
|
|
|
|
pgconn now uses non-blocking IO. This is a significant internal restructuring, but it should not cause any visible changes on its own. However, it is important in implementing other new features.
|
|
|
|
`CheckConn()` checks a connection's liveness by doing a non-blocking read. This can be used to detect database restarts or network interruptions without executing a query or a ping.
|
|
|
|
pgconn now supports pipeline mode.
|
|
|
|
`*PgConn.ReceiveResults` removed. Use pipeline mode instead.
|
|
|
|
`Timeout()` no longer considers `context.Canceled` as a timeout error. `context.DeadlineExceeded` still is considered a timeout error.
|
|
|
|
## pgxpool
|
|
|
|
`Connect` and `ConnectConfig` have been renamed to `New` and `NewWithConfig` respectively. The `LazyConnect` option has been removed. Pools always lazily connect.
|
|
|
|
## pgtype
|
|
|
|
The `pgtype` package has been significantly changed.
|
|
|
|
### NULL Representation
|
|
|
|
Previously, types had a `Status` field that could be `Undefined`, `Null`, or `Present`. This has been changed to a
|
|
`Valid` `bool` field to harmonize with how `database/sql` represents `NULL` and to make the zero value useable.
|
|
|
|
Previously, a type that implemented `driver.Valuer` would have the `Value` method called even on a nil pointer. All nils
|
|
whether typed or untyped now represent `NULL`.
|
|
|
|
### Codec and Value Split
|
|
|
|
Previously, the type system combined decoding and encoding values with the value types. e.g. Type `Int8` both handled
|
|
encoding and decoding the PostgreSQL representation and acted as a value object. This caused some difficulties when
|
|
there was not an exact 1 to 1 relationship between the Go types and the PostgreSQL types For example, scanning a
|
|
PostgreSQL binary `numeric` into a Go `float64` was awkward (see https://github.com/jackc/pgtype/issues/147). This
|
|
concepts have been separated. A `Codec` only has responsibility for encoding and decoding values. Value types are
|
|
generally defined by implementing an interface that a particular `Codec` understands (e.g. `PointScanner` and
|
|
`PointValuer` for the PostgreSQL `point` type).
|
|
|
|
### Array Types
|
|
|
|
All array types are now handled by `ArrayCodec` instead of using code generation for each new array type. This also
|
|
means that less common array types such as `point[]` are now supported. `Array[T]` supports PostgreSQL multi-dimensional
|
|
arrays.
|
|
|
|
### Composite Types
|
|
|
|
Composite types must be registered before use. `CompositeFields` may still be used to construct and destruct composite
|
|
values, but any type may now implement `CompositeIndexGetter` and `CompositeIndexScanner` to be used as a composite.
|
|
|
|
### Range Types
|
|
|
|
Range types are now handled with types `RangeCodec` and `Range[T]`. This allows additional user defined range types to
|
|
easily be handled. Multirange types are handled similarly with `MultirangeCodec` and `Multirange[T]`.
|
|
|
|
### pgxtype
|
|
|
|
`LoadDataType` moved to `*Conn` as `LoadType`.
|
|
|
|
### Bytea
|
|
|
|
The `Bytea` and `GenericBinary` types have been replaced. Use the following instead:
|
|
|
|
* `[]byte` - For normal usage directly use `[]byte`.
|
|
* `DriverBytes` - Uses driver memory only available until next database method call. Avoids a copy and an allocation.
|
|
* `PreallocBytes` - Uses preallocated byte slice to avoid an allocation.
|
|
* `UndecodedBytes` - Avoids any decoding. Allows working with raw bytes.
|
|
|
|
### Dropped lib/pq Support
|
|
|
|
`pgtype` previously supported and was tested against [lib/pq](https://github.com/lib/pq). While it will continue to work
|
|
in most cases this is no longer supported.
|
|
|
|
### database/sql Scan
|
|
|
|
Previously, most `Scan` implementations would convert `[]byte` to `string` automatically to decode a text value. Now
|
|
only `string` is handled. This is to allow the possibility of future binary support in `database/sql` mode by
|
|
considering `[]byte` to be binary format and `string` text format. This change should have no effect for any use with
|
|
`pgx`. The previous behavior was only necessary for `lib/pq` compatibility.
|
|
|
|
Added `*Map.SQLScanner` to create a `sql.Scanner` for types such as `[]int32` and `Range[T]` that do not implement
|
|
`sql.Scanner` directly.
|
|
|
|
### Number Type Fields Include Bit size
|
|
|
|
`Int2`, `Int4`, `Int8`, `Float4`, `Float8`, and `Uint32` fields now include bit size. e.g. `Int` is renamed to `Int64`.
|
|
This matches the convention set by `database/sql`. In addition, for comparable types like `pgtype.Int8` and
|
|
`sql.NullInt64` the structures are identical. This means they can be directly converted one to another.
|
|
|
|
### 3rd Party Type Integrations
|
|
|
|
* Extracted integrations with https://github.com/shopspring/decimal and https://github.com/gofrs/uuid to
|
|
https://github.com/jackc/pgx-shopspring-decimal and https://github.com/jackc/pgx-gofrs-uuid respectively. This trims
|
|
the pgx dependency tree.
|
|
|
|
### Other Changes
|
|
|
|
* `Bit` and `Varbit` are both replaced by the `Bits` type.
|
|
* `CID`, `OID`, `OIDValue`, and `XID` are replaced by the `Uint32` type.
|
|
* `Hstore` is now defined as `map[string]*string`.
|
|
* `JSON` and `JSONB` types removed. Use `[]byte` or `string` directly.
|
|
* `QChar` type removed. Use `rune` or `byte` directly.
|
|
* `Inet` and `Cidr` types removed. Use `netip.Addr` and `netip.Prefix` directly. These types are more memory efficient than the previous `net.IPNet`.
|
|
* `Macaddr` type removed. Use `net.HardwareAddr` directly.
|
|
* Renamed `pgtype.ConnInfo` to `pgtype.Map`.
|
|
* Renamed `pgtype.DataType` to `pgtype.Type`.
|
|
* Renamed `pgtype.None` to `pgtype.Finite`.
|
|
* `RegisterType` now accepts a `*Type` instead of `Type`.
|
|
* Assorted array helper methods and types made private.
|
|
|
|
## stdlib
|
|
|
|
* Removed `AcquireConn` and `ReleaseConn` as that functionality has been built in since Go 1.13.
|
|
|
|
## Reduced Memory Usage by Reusing Read Buffers
|
|
|
|
Previously, the connection read buffer would allocate large chunks of memory and never reuse them. This allowed
|
|
transferring ownership to anything such as scanned values without incurring an additional allocation and memory copy.
|
|
However, this came at the cost of overall increased memory allocation size. But worse it was also possible to pin large
|
|
chunks of memory by retaining a reference to a small value that originally came directly from the read buffer. Now
|
|
ownership remains with the read buffer and anything needing to retain a value must make a copy.
|
|
|
|
## Query Execution Modes
|
|
|
|
Control over automatic prepared statement caching and simple protocol use are now combined into query execution mode.
|
|
See documentation for `QueryExecMode`.
|
|
|
|
## QueryRewriter Interface and NamedArgs
|
|
|
|
pgx now supports named arguments with the `NamedArgs` type. This is implemented via the new `QueryRewriter` interface which
|
|
allows arbitrary rewriting of query SQL and arguments.

## RowScanner Interface
|
|
|
|
The `RowScanner` interface allows a single argument to Rows.Scan to scan the entire row.
|
|
|
|
## Rows Result Helpers
|
|
|
|
* `CollectRows` and `RowTo*` functions simplify collecting results into a slice.
|
|
* `CollectOneRow` collects one row using `RowTo*` functions.
|
|
* `ForEachRow` simplifies scanning each row and executing code using the scanned values. `ForEachRow` replaces `QueryFunc`.
|
|
|
|
## Tx Helpers
|
|
|
|
Rather than every type that implemented `Begin` or `BeginTx` methods also needing to implement `BeginFunc` and
|
|
`BeginTxFunc` these methods have been converted to functions that take a db that implements `Begin` or `BeginTx`.
|
|
|
|
## Improved Batch Query Ergonomics
|
|
|
|
Previously, the code for building a batch went in one place before the call to `SendBatch`, and the code for reading the
|
|
results went in one place after the call to `SendBatch`. This could make it difficult to match up the query and the code
|
|
to handle the results. Now `Queue` returns a `QueuedQuery` which has methods `Query`, `QueryRow`, and `Exec` which can
|
|
be used to register a callback function that will handle the result. Callback functions are called automatically when
|
|
`BatchResults.Close` is called.
|
|
|
|
## SendBatch Uses Pipeline Mode When Appropriate
|
|
|
|
Previously, a batch with 10 unique parameterized statements executed 100 times would entail 11 network round trips. 1
|
|
for each prepare / describe and 1 for executing them all. Now pipeline mode is used to prepare / describe all statements
|
|
in a single network round trip. So it would only take 2 round trips.
|

|
## Tracing and Logging
|
|
|
|
Internal logging support has been replaced with tracing hooks. This allows custom tracing integration with tools like OpenTelemetry. Package tracelog provides an adapter for pgx v4 loggers to act as a tracer.
|
|
|
|
All integrations with 3rd party loggers have been extracted to separate repositories. This trims the pgx dependency
|
|
tree.
