In this specific case (data warehouse app), multiple machines is the
better bet. Load data on 1 machine, copy to other servers and then use a
middleman to spread out SQL statements to each machine.

I was going to suggest pgpool as the middleman but I believe it's
limited to 2 machines max at this time. I suppose you could daisy chain
pgpools running on every machine.
