What I'm pointing out is that you can't actually do that. You think you can, but you can't. Instead, what you need to do is: 1) Recover to target_time. 2) Pause 3) shut down the replica 4) replace recovery.conf with one which streams 5) restart replica This is consistent behavior and makes sense when you think about it. So I think what we need to do is clarify in the documentation covering recovery_target and standby_mode that they are exclusive. Hmmm. You know, I think this means we do have a bug. If recovery_target_time and standby_mode are exclusive, we should error if the user attempts to set them both. -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
