I have a lot of respect for pgbouncer (haven't used pgpool). One possible way to do what you're thinking is to rotate the pool on user. In bouncer each database role gets its own pool (if you understand how transaction mode works you can see why it has to work this way). Not sure if this is helpful. Why are you trying to separate the pools like that? merlin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
