Changelog

Sourced from github.com/jackc/pgx/v5's changelog.

5.9.0 (March 21, 2026)

This release includes a number of new features such as SCRAM-SHA-256-PLUS support, OAuth authentication support, and PostgreSQL protocol 3.2 support.

It significantly reduces the amount of network traffic when using prepared statements (which are used automatically by default) by avoiding unnecessary Describe Portal messages. This also reduces local memory usage.

It also includes multiple fixes for potential DoS due to panic or OOM if connected to a malicious server that sends deliberately malformed messages.

• Require Go 1.25+
• Add SCRAM-SHA-256-PLUS support (Adam Brightwell)
• Add OAuth authentication support for PostgreSQL 18 (David Schneider)
• Add PostgreSQL protocol 3.2 support (Dirkjan Bussink)
• Add tsvector type support (Adam Brightwell)
• Skip Describe Portal for cached prepared statements reducing network round trips
• Make LoadTypes query easier to support on "postgres-like" servers (Jelte Fennema-Nio)
• Default empty user to current OS user matching libpq behavior (ShivangSrivastava)
• Optimize LRU statement cache with custom linked list and node pooling (Mathias Bogaert)
• Optimize date scanning by replacing regex with manual parsing (Mathias Bogaert)
• Optimize pgio append/set functions with direct byte shifts (Mathias Bogaert)
• Make RowsAffected faster (Abhishek Chanda)
• Fix: Pipeline.Close panic when server sends multiple FATAL errors (Varun Chawla)
• Fix: ContextWatcher goroutine leak (Hank Donnay)
• Fix: stdlib discard connections with open transactions in ResetSession (Jeremy Schneider)
• Fix: pipelineBatchResults.Exec silently swallowing lastRows error
• Fix: ColumnTypeLength using BPCharArrayOID instead of BPCharOID
• Fix: TSVector text encoding returning nil for valid empty tsvector
• Fix: wrong error messages for Int2 and Int4 underflow
• Fix: Numeric nil Int pointer dereference with Valid: true
• Fix: reversed strings.ContainsAny arguments in Numeric.ScanScientific
• Fix: message length parsing on 32-bit platforms
• Fix: FunctionCallResponse.Decode mishandling of signed result size
• Fix: returning wrong error in configTLS when DecryptPEMBlock fails (Maxim Motyshen)
• Fix: misleading ParseConfig error when default_query_exec_mode is invalid (Skarm)
• Fix: missed Unwatch in Pipeline error paths
• Clarify too many failed acquire attempts error message
• Better error wrapping with context and SQL statement (Aneesh Makala)
• Enable govet and ineffassign linters (Federico Guerinoni)
• Guard against various malformed binary messages (arrays, hstore, multirange, protocol messages)
• Fix various godoc comments (ferhat elmas)
• Fix typos in comments (Oleksandr Redko)

5.8.0 (December 26, 2025)

• Require Go 1.24+
• Remove golang.org/x/crypto dependency
• Add OptionShouldPing to control ResetSession ping behavior (ilyam8)
• Fix: Avoid overflow when MaxConns is set to MaxInt32

Changed

• Introduce the EMPTY Type in go.opentelemetry.io/otel/attribute to reflect that an empty value is now a valid value, with INVALID remaining as a deprecated alias of EMPTY. (#8038)
