* fix(checkpointer): use AsyncConnectionPool for postgres to prevent stale connection errors (#3223) Replace AsyncPostgresSaver.from_conn_string() with an explicit AsyncConnectionPool that has check_connection enabled, so dead idle connections are detected and replaced on checkout instead of raising OperationalError. * Potential fix for pull request finding Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> * Fixed the unit test error and lint error * fix(checkpointer): add TCP keepalive to postgres connection pool (#3254) Enable TCP keepalive probes on the AsyncConnectionPool to prevent idle postgres connections from being dropped by the server or network middleware. Combined with the existing check_connection callback, this provides defense-in-depth against stale connection errors. Fixes #3254 * Changed the code as review suggestion --------- Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com> |
