You can't do this with streaming replication. But you can with slony. Just replicate from 9.1 as master to 9.2 as a slave. Once they are fully in sync, promote 9.2 to master. Note that you will have to restart postgres at least once to move the 9.2 port to the same as the 9.1 port when you switch. SO it won't be zero down time, but pretty darn close. - Chris -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
