I don't know of a preconfigured solution. Generally speaking, the best
configuration will be highly dependent on your hardware, data, and
application.

There are many Linux and other OS distributions that will work just
fine. You may need to tweak a few kernel configuration parameters, but
that's not too difficult; see:
http://www.postgresql.org/docs/view.php?version=7.3&idoc=0&file=kernel-resources.html

I would *not* use the default version of Postgres shipped with any
particular distribution. Use 7.3.3 because that is the latest released
version. Or, as Shridhar mentioned in his post, the are a number of
pretty significant performance improvements in 7.4 (which is in feature
freeze and scheduled to go into beta on 21 July). If you are in an
exploratory/test phase rather than production right now, I'd say use the
7.4 beta for your comparisons.

If money is truly not a problem, but time is, my advice is to hire a
consultant. There are probably several people on this list that can fill
that role for you. Otherwise read the archives and ask lots of specific
questions.
