Adjust pg_wal_replay_wait() procedure behavior on promoted standby pg_wal_replay_wait() is intended to be called on standby. However, standby can be promoted to primary at any moment, even concurrently with the pg_wal_replay_wait() call. If recovery is not currently in progress that doesn't mean the wait was unsuccessful. Thus, we always need to recheck if the target LSN is replayed.
