Slony works like this. You set up a replication cluster, define your
nodes, and define the communication between these nodes (much simpler
with 1.1). You then set up sets which contain tables and sequences. You
specify a single provider for a given set, then subscribe it to other
nodes (called subscribers). When you subscribe a set, it will empty all
the tables in that set on the subscriber, and copy in the data in from
the provider.

Setting up slony will involve some work on your part. It's not the kind
of tool where you can get quick answers about how to configure it.
You'll need to have a look at the docs, and plan a deployment based on
you own system. I would recommend running through the sample setup,
figuring out how the thing works, and then start thinking about how you
would deploy it for your own database(s). This list is a great resource
for getting help with the specifics, but for broad, "how does it work
questions", well, that's what the docs and the admin guide are for.

These two links should get you started.

A Window port is happening, but I haven't been following the progress.
