[GENERAL] RETURNS SETOF RECORD with 1 column

Hi all.

Please, see this fragment:

DROP TABLE IF EXISTS atable;
CREATE TABLE atable (
 atext TEXT,
 anint INT
);

TRUNCATE atable;
INSERT INTO atable VALUES
 ( 'one',1 ),
 ( 'two',2 ),
 ( 'three',3 ),
 ( 'four',4 )
;

CREATE OR REPLACE FUNCTION afun1( OUT ot TEXT )
RETURNS SETOF RECORD
LANGUAGE PLPGSQL
AS $l0$
BEGIN
 RETURN QUERY SELECT atext FROM atable;
END;
$l0$;

CREATE OR REPLACE FUNCTION afun2( OUT ot TEXT, OUT oi INT )
RETURNS SETOF RECORD
LANGUAGE PLPGSQL
AS $l0$
BEGIN
 RETURN QUERY SELECT atext,anint FROM atable;
END;
$l0$;

I am not allowed to create afun1() but can create and use afun2().
The error message for afun1() reads:

ERROR:  function result type must be text because of OUT parameters

The idea I understand is that a RECORD must have no less than TWO columns.
Of course it's not a problem to declare "RETURNS SETOF TEXT", but why
forcing me to "deviate" from a very general construct for a 1 column
case?

Is this a bug/enhancement or am I missing something?

TALIA!
