Unless I'm missing something, you can use pg_basebackup -x for the standby. If lots of WAL files are generated in the master after pg_basebackup -x ends and before you start the standby instance, you may get the following error. In this case, you need to consult with archived WAL files even though you specified -x option in pg_basebackup. > FATAL: could not receive data from WAL stream: FATAL: requested WAL > segment 00000001000000000000005C has already been removed Though we have the above problem, pg_basebackup -x is usable for the standby, I think.
