In autovacuum.c, autovacuum workers avoid waiting for the standby by doing:
/* * Force synchronous replication off to allow regular maintenance even if * we are waiting for standbys to connect.
Thisis important to ensure we * aren't blocked from performing anti-wraparound tasks. */if (synchronous_commit >
SYNCHRONOUS_COMMIT_LOCAL_FLUSH)SetConfigOption("synchronous_commit", "local", PGC_SUSET, PGC_S_OVERRIDE);
