You might want to check out Slony-I <http://www.slony.info> for the
purpose of upgrading. Slony is actually a replication engine, but it can
be used to upgrade with little or no downtime. Otherwise, just
dump/upgrade/restore like normal.
As far as compatibility, 8.0 should be mostly backwards compatible.
There may be some minor things that I don't know about, so I recommend
some testing first.
