I haven't quite gotten to replication myself.  However, on the admin list it is a feature that
comes up pretty often.  Also, Point In Time Recovery (PITR) seems to be a popular subject lately

this page describe a synchronous solution.

This thread discusses a little bit about how Slony work.

From what I've read,  Slony can be used to do the following things:

1. provide a secondary server in as a hot standby in case of primary server failure
2. Provide 1 Primary server for inserts/updates/delete and one or more secondary servers for
reporting from selects.  I would imagine that the writing server would be optimized for heavy
writing while the reporting servers would be optimized for quick queries.  However, IIRC only the
primary server can be written to.

I'll defer this question for someone with more experience. :-)
