Found small issue with OUT params

Hi,
consider this function:

CREATE OR REPLACE FUNCTION FIND_USER_SOCKET_BYNAME (
IN IN_USERNAME VARCHAR,
OUT OUT_SOCKET_ADDRESS INTEGER)
AS
$BODY$
BEGIN
select socket_address from userdata where fullname = in_username into
out_socket_address;

if out_socket_address is null then
out_socket_address = 0 ;
end if;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE

If I call it like this:
select * from FIND_USER_SOCKET_BYNAME('juser');

I would expect to get back 1 value with the name of the OUT param
(OUT_SOCKET_ADDRESS).
However it comes back with the name of the function which I would expect
if I called it like this:

select FIND_USER_SOCKET_BYNAME('juser');

If I add another OUT value then the value comes back with the name of
the out param(plus the temp one I added) as expected.

It's easy enough to work around, but was not as expected.

Thanks,
