this create the same error:
ERROR:  return type mismatch in function declared to return foo
DETAIL:  Final SELECT returns too few columns.
CONTEXT:  SQL function "getfoo

I try with:
CREATE FUNCTION getfoo (IN int, OUT int, OUT int) AS $$
    SELECT fooid, foosubid FROM foo WHERE fooid = $1;
$$ LANGUAGE SQL;

but only one row returned...

Looking for other tips!

Thanks,
