problem, the user might not realize he's got one until he starts to wonder
why autovac/autoanalyze aren't working.
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. This is 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);
