Yeah, I was thinking about that myself - the existing design presumes
that the only possible reason for failure of pqAddTuple is OOM, but
it'd be better to distinguish "too many tuples" from true OOM. So
we should also refactor to make pqAddTuple responsible for setting
the error message. Might be best to do the refactoring first.
