Are you talking a big multi-way setup? That's rather complex, and
resolution of conflicting updates can keep a DBA busy full time in a
poorly thought out setup.
OTOH, if you're looking at having one or more one-way pushes in your
setup, you might want to look at using slony. There are a lot of ways
you can set it up, depending on your needs. Got a bit more detail on
what you're wanting to do?
