Bumps github.com/jackc/pgx/v5 from 5.8.0 to 5.9.2.

Changelog

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

5.9.2 (April 18, 2026)

Fix SQL Injection via placeholder confusion with dollar quoted string literals (GHSA-j88v-2chj-qfwx)

SQL injection can occur when:

The non-default simple protocol is used.

A dollar quoted string literal is used in the SQL query.

That query contains text that would be would be interpreted outside as a placeholder outside of a string literal.

The value of that placeholder is controllable by the attacker.

e.g.
attackValue := `$tag$; drop table canary; --`
_, err = tx.Exec(ctx, `select $tag$ $1 $tag$, $1`, pgx.QueryExecModeSimpleProtocol, attackValue)
This is unlikely to occur outside of a contrived scenario.

5.9.1 (March 22, 2026)

Fix: batch result format corruption when using cached prepared statements (reported by Dirkjan Bussink)

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)
