the overall idea expressed is doable.
following are comments

1. you have to put RETURNS setof TT (if you plan to return TT) since you used RETURN NEXT
2.  you have to use SELECT INTO rec  in the function where rec is rowtype TT

4. its not a good etiquette to address email to someone and mark Cc to a list.
