Any database that has real ACID guarantees is going to be complex. Some more than others. I think that upgrading postgresql in place is a LOT of work and not the highest priority, and slony lets you upgrade LIVE. Note that you cannot upgrade an Oracle installation from 9g to 10i live. You take it offline from the app, migrate your data, and start up the new database. Slony replication lets postgresql accomplish this, which is really quite impressive. We just upgraded from an 8.1 server to an 8.3 server via slony, and it went smooth as silk. db downtime was measured in seconds. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
