CREATE TABLE foos
(
     foo text PRIMARY KEY
     , title text NOT NULL
);

INSERT INTO foos (foo, title) values
('foo', 'the great')
, ('bar', 'the extravagant')
, ('baz', 'the indisputable');

CREATE OR REPLACE FUNCTION get_foo() RETURNS record
LANGUAGE plpgsql AS $body$
DECLARE
   v_record record;
BEGIN
     SELECT INTO v_record
         *
     FROM foos
     ORDER BY RANDOM()
     LIMIT 1;
     RETURN v_record;
END;
$body$;

   a  |        b
-----+------------------
baz | the indisputable
(1 row)

test=#      SELECT *
test-# FROM get_foo() AS (a text, b text);
   a  |        b
-----+-----------------
bar | the extravagant
(1 row)

IIRC, this form is used by the crosstab functions in tablefunc.
