This is not completely true, you can always use something like pgbouncer or other middleware to change the server to which clients connect. you still need to solve the fact that you will have a read-only server at the other side. something like repmgr + pgbouncer will work fine. i agree that once/if we ever have multimaster included then this could be a good idea -- Jaime Casanova www.2ndQuadrant.com Professional PostgreSQL: Soporte 24x7 y capacitación -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
