Please try this interactively in a psql session:

CREATE FUNCTION sleep(interval) RETURNS integer AS '
DECLARE
  endtime timestamp;
BEGIN
  endtime := timeofday()::timestamp + $1;
  WHILE timeofday()::timestamp < endtime LOOP
  END LOOP;
  RETURN 0;
END;
' LANGUAGE 'plpgsql';

SELECT timeofday();
SELECT timeofday()::timestamp;
-- wait a few seconds ...
SELECT timeofday()::timestamp;
SELECT timeofday()::timestamp + '0:0:2'::interval;

SELECT sleep('0:0:2'::interval);

... and tell us what happens.
