5 Oct 2026 Intermittent PgBouncer login rejections caused by IPv6 localhost resolution

Problem: A production PostgreSQL 15.17 cluster managed by Patroni 3.3.2, with PgBouncer 1.25.1 in front of it, showed intermittent application failures during night operations. The application logged ODBC connection errors with SQLSTATE 08P01: “server login has been failing, cached error: connect failed (server_login_retry)”. The customer suspected PostgreSQL connection exhaustion. Metrics showed otherwise: max_connections was 4,000 […]
