This was nearly the same code. Extend wait_for_catchup to allow waiting for pg_current_wal_lsn() and use that in the subscription tests. Also change one use in the pg_rewind tests to use this. Also remove some broken code in wait_for_catchup and wait_for_slot_catchup. The error message in case the waiting failed wanted to show the current LSN, but the way it was written never worked. So since nobody ever cared, just remove it. Reviewed-by: Michael Paquier <michael.paquier@gmail.com>
