Joe, I'm working on the comparison--I think the best way to do it is to reload the original data into a new database and compare them, so it will take a while. I have tuned postgresql.conf according to the page that everybody around here seems to cite. I'll probably post back tomorrow with another set of results. Also, the perl script that did several queries used lengths of 5000, 10,000 and 40,000 because those are the typical lengths I would use (occasionally shorter).
