DBD::Pg 1.40, also perl-DBI-1.40 and perl-5.8.5.  Greg Mullane
promised he'd take a closer look after he gets done moving to
Florida... in the meantime, I have a self-contained test case
if someone else wants to dig into it.

(Greg indicated that he thought the coding style in the Perl
test script pretty well sucked, which I don't doubt, but the
question remains why we are so much slower than MySQL on the
same code.)
