You may do this :

 SELECT DATE (DATE '2003-04-01' + INTERVAL '24:00:00');


or build a PL/PGSQL function as this :

 CREATE FUNCTION onedaymore(DATE) RETURNS DATE AS '
   DECLARE
   olddate ALIAS FOR $1;
   newdate date;
   BEGIN
     newdate :=  olddate + INTERVAL ''24:00:00'';
     RETURN
newdate;
   END;
 '  LANGUAGE 'plpgsql';
