Recommended action: Configure ConnectionPool(check=ConnectionPool.check_connection) (psycopg_pool >= 3.2) and set max_idle/max_lifetime below the server/proxy idle timeout; retry idempotent reads once. Option: Enable pool connection checks [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. ConnectionPool(conninfo, check=ConnectionPool.check_connection, max_idle=..., max_lifetime=...) 2. Keep max_idle shorter than server idle_session_timeout / proxy idle timeout Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
