# TEST Replication, recovery and applying log records immediately.
# TEST Master and 1 client. Start up both sites.
# TEST Close client and run rep_test on the master so that the
# TEST log record is the same LSN the client would be expecting.
# TEST Reopen client with recovery and verify the client does not
# TEST try to apply that "expected" record before it synchronizes
# TEST with the master.
