Bumps github.com/jackc/pgx/v5 from 5.9.2 to 5.10.0.

Changelog

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

5.10.0 (June 3, 2026)

This release includes a significant amount of hardening against malicious or compromised PostgreSQL servers, contributed by Sean Chittenden at CrowdStrike, Inc. This work bounds binary decoders against attacker-controlled message sizes, caps server-supplied SCRAM iteration counts, adds require_auth to restrict which authentication methods a server may use (mitigating downgrade attacks under sslmode=prefer), and ensures cancellation requests are sent over TLS when the original connection used TLS.

Features

  • Add require_auth to restrict accepted server authentication methods (Sean Chittenden at CrowdStrike, Inc.)
  • Add ParseConfigOptions.ConnStringAllowedKeys to restrict allowed connection string keys (Sean Chittenden at CrowdStrike, Inc.)
  • Add StructArgs and StrictStructArgs for @-named queries (Tubelight30)
  • Add ErrConnClosed sentinel error and unwrap it from connLockError (Charlie Tonneslan)
  • pgxpool: check if connection is expired before acquire (arthurdotwork)

Security Hardening

  • Encrypt CancelRequest connection when the primary connection used TLS (Sean Chittenden at CrowdStrike, Inc.)
  • Cap server-supplied SCRAM iteration count (Sean Chittenden at CrowdStrike, Inc.)
  • Default Frontend max message body length to ~1 GiB (Sean Chittenden at CrowdStrike, Inc.)
  • Bound hstore binary decode against malicious server input (Sean Chittenden at CrowdStrike, Inc.)
  • Bound array binary decode element length against remaining message bytes (Sean Chittenden at CrowdStrike, Inc.)
  • Bound array element count against remaining message bytes (Sean Chittenden at CrowdStrike, Inc.)
  • Bound range, multirange, and tsvector binary decoders (Sean Chittenden at CrowdStrike, Inc.)
  • Document secure connection configuration (Sean Chittenden at CrowdStrike, Inc.)
  • Fix panic on malformed geometric text; return an error instead (MaIII)

Fixes

  • Fix scanning "char" (OID 18) into *string in binary format (luongs3)
  • Fix handling of typed-nil driver.Valuer in array and composite codecs (Donncha Fahy)
  • Fix CopyData.Data hex decoding in UnmarshalJSON (Charlie Tonneslan)
  • Fix data race when context is cancelled during connect
  • Fix parseKeywordValueSettings rejecting trailing whitespace (alliasgher)
  • pgconn: preserve full error chain in normalizeTimeoutError (Charlie Tonneslan)
  • pgconn: use a fresh context for the fallback connection in connectPreferred (Charlie Tonneslan)
  • pgxpool: fix MaxLifetimeDestroyCount and ping order for acquire-time expiry check
  • Add missing error check of rows.Err to load types (Jen Altavilla)

PR Summary

Low Risk
Lockfile-only change with no app code edits; minor driver upgrade may subtly affect connection/auth/pooling behavior for existing PostgreSQL usage.

Overview
Bumps github.com/jackc/pgx/v5 from 5.9.2 to 5.10.0 in go.mod and go.sum only—no application source changes.

The new pgx release mainly hardens the PostgreSQL client against malicious or compromised servers (message size bounds, SCRAM iteration caps, TLS for cancel requests, optional require_auth), plus pool and codec fixes. The repo still uses pgx through database/sql (e.g. inventory service’s pgx stdlib driver); behavior should stay the same unless you opt into new connection options.
