From e3e29cec10d15bbcedc6b41887d8f4e138d719bd Mon Sep 17 00:00:00 2001 From: Fujii Masao Date: Tue, 12 Oct 2021 09:50:17 +0900 Subject: [PATCH] Make autovacuum launcher more responsive to pg_log_backend_memory_contexts(). Previously when pg_log_backend_memory_contexts() sent the request to the autovacuum launcher, it could take more than several seconds to log its memory contexts. Because the function (HandleAutoVacLauncherInterrupts) to process any new interrupts that autovacuum launcher received didn't handle the request for logging of memory contexts. This commit changes the function so that it handles the request, to make autovacuum launcher more responsitve to pg_log_backend_memory_contexts(). Back-patch to v14 where pg_log_backend_memory_contexts() was added.
