streaming replication? I promoted secondary server and now I want to go to old setup .how can I bring up my old master in line.. please share the failback procedure.
It depends of what is your high availability architecture and what tools are you using. But you should look at pg_rewind or pg_basebackup in order to resync your old master as new standby node.
We don't use any tools. How can I use pg_rewind? Could you share me the command?
