Обсуждение: failover and switchover in postgresql
Dear Community! For example, I have two servers. First is the primary server and second is the slave server. I need slave server to become primary (temp) during primary server is down. Then old primary was fixed. I need old primary server is the primary server and then old slave server (new primary (temp)) to become slave server. Pls help me to explain how solve this problem.

After performing a failover, the old slave becomes the new master, but the opposite is not true, that is, the old master does not automatically become the slave. You will need to set up replication from the new master to the to-be slave to be able to switch back.

The very first thing you need to do is specify your version of PostgreSQL, because these features have seen significant changesin recent releases. If you're just getting started, and can use the latest version, that would be best--and you need to say so... -- Scott Ribe scott_ribe@elevated-dev.com http://www.elevated-dev.com/ (303) 722-0567 voice
