Works fine for me:

regression=# CREATE FUNCTION add_one (integer) RETURNS INTEGER AS '
regression'#     BEGIN
regression'#         RETURN $1 + 1;
regression'#     END;
regression'# ' LANGUAGE 'plpgsql';
CREATE FUNCTION
regression=# select add_one(10);
 add_one
---------
      11
(1 row)

Perhaps you should show us exactly what you did.
