Ok, then pl/pgsql and pl/python (which can't return SETOF) are ruled out.
(Thank you for pointing that out).
But pl/perl seems to do the trick:

"PL/Perl functions can also return sets of either scalar or composite types.
Usually you'll want to return rows one at a time, both to speed up startup
time and to keep from queueing up the entire result set in memory"

Any other issues anyone can think about?
