Duh, brain fade on my part, sorry. Still, I suspect the return type of
PQntuples would be the very least of the changes we'd need to make to
support resultsets > 2G rows. And I would not advise changing it to an
unsigned type, since that could cause hard-to-find breakage in
comparison logic in applications.
