Well, what happens now in previous versions with pg_standby et al is that the standby starts up. That doesn't seem appropriate either. Hmm, it would be trivial to just stay in the standby mode at a corrupt file, continuously retrying to restore it and continue replay. If it's genuinely corrupt, it will never succeed and the standby gets stuck at that point. Maybe that's better; it's close to what Fujii suggested except that you don't need a new mode for it. I'm worried that the administrator won't notice the error promptly because at a quick glance the server is up and running, while it's actually stuck at the error and falling indefinitely behind the master. Maybe if we make it a WARNING, that's enough to alleviate that. It's true that if the standby is actively being used for read-only queries, shutting it down to just get the administrators attention isn't good either. -- Heikki Linnakangas EnterpriseDB http://www.enterprisedb.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
