Fix synchronized_standby_slots GUC check hook The validate_sync_standby_slots subroutine requires an LWLock, so it cannot run in processes without PGPROC; skip it there to avoid a crash.
This replaces the current test for ReplicationSlotCtl being not null, which appears to be a solution for the same problem but less general. I also rewrote a related comment that mentioned ReplicationSlotCtl in StandbySlotsHaveCaughtup. This code came in with commit bf279ddd1c28; backpatch to 17.
