Found small issue with OUT params

[Tony Caduto <tony_caduto(at)amsoftwaredesign(dot)com>]

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,
