Slony is an open source replication system built for Postgres.
But the real problem is that you are doing a vaccum full every day.
This is highly invasive.
Take a look at the postgres docs on Vacuuming the db. Analyze is best
on a daily basis. If you have a lot of deletes, then try vacuum
truncate.

The postgres documentation describes the various vaccuum options and
explains the merits of each.

Hope that helps.
