It would not be necessarily on the fly, at least in the first step we
possibly get away with declaraing the returned tuples at creation time
and implicitly creating those tuple types. The declaration could be like
"returns (touchedrows int, somethingelse datetime), setof (article int,
description text)" for a function/method that has two resultsets, one of
those with always one row.
