Re: Problem with pg_upgrade

The omnipitr-backup-slave process takes online backups from the standby,
and this is done everyday. This process connects to the master and calls a
pg_start_backup and then looks for a restore point on the standby after
that WAL address. So i don't think I need to shut down the server.

Also, it is the omnipitr-backup-slave process that makes a separate backup
for xlog.

If you run vacuumedb now, does everything later work fine?

I'm not sure about that. Didn't try anything else after that. The 9.2beta2
server starts without errors though.
