I'd upgrade to 7.2.1 and give everybody their own database. I've never
seen a problem with lots of seperate databases in postgresql, and we run
dozens on our production box (each program gets its own database).

Each empty database uses only about 1.7 megs of disc space, by the way, so
unless you're on a machine with a really small drive, having bunches of
databases shouldn't be any real problem.
