you can't have it both ways. at the time the function call is
executed, the return type/fields must be known. you can do this by
either a. explicitly defining the function return type or b.
describing the function return type in the function call, or c. use a
generic type to hold the output record structure which can be
parsed/dealt with later, like text or hstore.
