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.
