Yes, but that is what I was envisioning. As you point out, that's the
only sane way to make sure we have a good version of DBD::Pg with
which to test. As a side effect, it put libpq through some extra
paces as well. :)

*shrug* It's different, but it's the best solution to the problem at
hand. It wouldn't be built as part of Pg, only as part of the tests.

Sure, but it's the difference between waiting for someone to write something
(and then dealing with the invevitable bugs, tweaks, and enhancements), or
using a solid, known quantity (DBI + Test::More).
