I think that really depends on your workload. Are you going to have a dozen or so transactions running at a time? then regular postgresql is probably ok. If you're gonna be running only one or two big, fat, hairy reporting queries, then you might wanna look at the bizgress mpp version. Note that some queries lend themselves to parallel processing more than others.
