I see what you're doing, but I'm not quite sure how to adapt it to what
I'm doing. Here's simplified snippet of my code. Can elaborate on how
I can return a recordset and the output parameters.?

CREATE OR REPLACE FUNCTION Search (OUT TotalRecords int, OUT TotalPages int)
RETURNS SETOF record AS
$BODY$
TotalRecords := 10;
TotalPages := 1;

FOR myRecord IN
SELECT cols FROM searchResults
LOOP
RETURN NEXT myRecord;
END LOOP;

Thanks,
