Bug: Reverting Return Type

Hi,

Create a new function that uses a TABLE return type definition:

CREATE OR REPLACE FUNCTION testing(IN p_test bigint)
RETURNS TABLE (id int) AS
$BODY$
SELECT 1 AS id
$BODY$
LANGUAGE sql STABLE;

Expected Results
The return type retains the ID column name and continues to use a
TABLE for the result.

Actual Results
When viewed in pgAdmin3, it becomes:

CREATE OR REPLACE FUNCTION testing(IN p_test bigint)
RETURNS SETOF integer AS
$BODY$
SELECT 1 AS id
$BODY$
LANGUAGE sql STABLE
COST 100
ROWS 1000;

The TABLE return type definition has been replaced.

This has no immediate effect on the database, but any subsequent edits
to the function through pgAdmin could catch developers unaware.
