That's a really good point. It was originally written thinking we would
eventually be able to stream tuples rather than materialize them, but
given that many years have passed and we are no closer (I believe) to a
true streaming mode for SRFs, a tuplestore would be much cleaner.
Given that change, is there even any leak to even worry about? As long
as the PGresult object is created in the correct memory context, it
ought to get cleaned up automatically, no?
I can't promise to make this change before 15 October, but I will get to
it before the end of CF3.
