It is much easier to use OUT parameters rather than a record. If iteratively building a set of records (a table) use RETURN NEXT. If generating from a query, use RETURN QUERY. See:

Think:

CREATE OR REPLACE FUNCTION my_func(OUT a integer, OUT b varchar) RETURNS SETOF RECORD AS $$
BEGIN
    -- Assign a and b, RETURN NEXT, repeat. when done, RETURN.
END;
$$ LANGUAGE 'plpgsql';
