# 5.4.3 (August 5, 2023)
* 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)
# 5.3.1 (February 27, 2023)
* Fix: Support v4 and v5 stdlib in same program (Tomáš Procházka)
* Fix: sql.Scanner not being used in certain cases
* Add text format jsonpath support
* Fix: fake non-blocking read adaptive wait time
# 5.3.0 (February 11, 2023)
* Fix: json values work with sql.Scanner
* Fixed / improved error messages (Mark Chambers and Yevgeny Pats)
* Fix: support scan into single dimensional arrays
* Fix: MaxConnLifetimeJitter setting actually jitter (Ben Weintraub)
* Fix: driver.Value representation of bytea should be []byte not string
* Fix: better handling of unregistered OIDs
* CopyFrom can use query cache to avoid extra round trip to get OIDs (Alejandro Do Nascimento Mora)
* Fix: encode to json ignoring driver.Valuer
* Support sql.Scanner on renamed base type
* Fix: pgtype.Numeric text encoding of negative numbers (Mark Chambers)
* Fix: connect with multiple hostnames when one can't be resolved
* Upgrade puddle to remove dependency on uber/atomic and fix alignment issue on 32-bit platform
* Fix: scanning json column into **string
* Multiple reductions in memory allocations
* Fake non-blocking read adapts its max wait time
* Improve CopyFrom performance and reduce memory usage
* Fix: encode []any to array
* Fix: LoadType for composite with dropped attributes (Felix Röhrich)
* Support v4 and v5 stdlib in same program
* Fix: text format array decoding with string of "NULL"
* Prefer binary format for arrays
# 5.2.0 (December 5, 2022)
* `tracelog.TraceLog` implements the pgx.PrepareTracer interface. (Vitalii Solodilov)

pgtype automatically marshals and unmarshals data from json and jsonb PostgreSQL types.
Array Support
ArrayCodec implements support for arrays. If pgtype supports type T then it can easily support []T by registering an
ArrayCodec for the appropriate PostgreSQL OID. In addition, Array[T] type can support multi-dimensional arrays.
Composite Support
CompositeCodec implements support for PostgreSQL composite types. Go structs can be scanned into if the public fields of
the struct are in the exact order and type of the PostgreSQL type or by implementing CompositeIndexScanner and
CompositeIndexGetter.
Enum Support
PostgreSQL enums can usually be treated as text. However, EnumCodec implements support for interning strings which can
reduce memory usage.
Array, Composite, and Enum Type Registration
Array, composite, and enum types can be easily registered from a pgx.Conn with the LoadType method.

integrations.
Entirely New Type Support
New PostgreSQL Type Support
If the PostgreSQL type is not already supported then an OID / Codec mapping can be registered with Map.RegisterType.
There is no difference between a Codec defined and registered by the application and a Codec built in to pgtype. See any
of the Codecs in pgtype for Codec examples and for examples of type registration.
pgtype uses the PostgreSQL OID to determine how to encode or decode a value. pgtype supports array, composite, domain,
and enum types. However, any type created in PostgreSQL with CREATE TYPE will receive a new OID. This means that the OID
of each new PostgreSQL type must be registered for pgtype to handle values of that type with the correct Codec.
The pgx.Conn LoadType method can return a *Type for array, composite, domain, and enum types by inspecting the database
metadata. This *Type can then be registered with Map.RegisterType.
For example, the following function could be called after a connection is established:
func RegisterDataTypes(ctx context.Context, conn *pgx.Conn) error {
dataTypeNames := []string{
"foo",
"_foo",
"bar",
"_bar",
}
for _, typeName := range dataTypeNames {
dataType, err := conn.LoadType(ctx, typeName)
if err != nil {
return err
}
conn.TypeMap().RegisterType(dataType)
}
return nil
}
A type cannot be registered unless all types it depends on are already registered. e.g. An array type cannot be
registered until its element type is registered.
ArrayCodec implements support for arrays. If pgtype supports type T then it can easily support []T by registering an
ArrayCodec for the appropriate PostgreSQL OID. In addition, Array[T] type can support multi-dimensional arrays.
CompositeCodec implements support for PostgreSQL composite types. Go structs can be scanned into if the public fields of
the struct are in the exact order and type of the PostgreSQL type or by implementing CompositeIndexScanner and
CompositeIndexGetter.
Domain types are treated as their underlying type if the underlying type and the domain type are registered.
PostgreSQL enums can usually be treated as text. However, EnumCodec implements support for interning strings which can
reduce memory usage.
While pgtype will often still work with unregistered types it is highly recommended that all types be registered due to
an improvement in performance and the elimination of certain edge cases.
If an entirely new PostgreSQL type (e.g. PostGIS types) is used then the application or a library can create a new
Codec. Then the OID / Codec mapping can be registered with Map.RegisterType. There is no difference between a Codec
defined and registered by the application and a Codec built in to pgtype. See any of the Codecs in pgtype for Codec
examples and for examples of type registration.
