You should do that anyway, because on older releases, you really
don't want to lag the last dot-release -- there are usually some big
bugs that have been shaken out.

One thing that is really nice about using the Slony trick, by the
way, is that when you switchover to your upgraded system, you make
your old database into a replica too. That means that you have the
ability to roll back to the old release if, once you get the new
system into production use, you happen to find something you'd
overlooked.
