To upgrade PG, you just have to install the new version on every server and
restart the postmaster. That's all.

The replication won't be impacted.

You could upgrade Slony, also. In order to do that, you have to compile it on
every node, stop the replication, upgrade stored procedures with the "update
functions" directive, and the restart slon. That's it. You can have a look at
that page : http://slony.info/documentation/slonyupgrade.html
