Well, I was sure. And here it is again (from Tom Lane: )

You've misunderstood this completely.  We are not storing anything
essential in the table, we're just using its rowtype to describe the
function's composite-type result.

Personally I would have written the example using a composite type
to make this more clear:

CREATE TYPE test_func_type AS (id int, name text);

CREATE FUNCTION test_func() RETURNS SETOF test_func_type AS $$
   SELECT 1, 'me' UNION ALL SELECT 2, 'you'
$$ LANGUAGE sql;

select * from test_func();
  id | name
----+------
   1 | me
   2 | you
(2 rows)

When this isnt what you want, you are out of options I fear.
Maybe you would write an example of how your hypotetical
function should act?
