Hi Tom,
psql --version returns 8.4devel. I would in fact like to try a newer snapshot, but I'm not sure how to get one. The devel snapshot 'one-click-installer' link provided at postgresql.org gives a 2009-01-01 version with no options for anything newer or older. I was thinking my next step would be to build from source by grabbing the next daily snapshot. Is this the thing to do?
Regards,
Daniel
