* pgsql: aio: Fix configuration reload in IO workers. @ 2025-07-12 04:38 Thomas Munro <tmunro@postgresql.org> 0 siblings, 0 replies; 2+ messages in thread From: Thomas Munro @ 2025-07-12 04:38 UTC (permalink / raw) To: pgsql-committers@lists.postgresql.org aio: Fix configuration reload in IO workers. method_worker.c installed SignalHandlerForConfigReload, but it failed to actually process reload requests. That hasn't yet produced any concrete problem reports in terms of GUC changes it should have cared about in v18, but it was inconsistent. It did cause problems for a couple of patches in development that need IO workers to react to ALTER SYSTEM + pg_reload_conf(). Fix extracted from one of those patches. Back-patch to 18.
