Missing RULEs from VIEWs and their format

Hi developers!

I have just filed ticket #167 concerning missing RULEs with VIEWs.
On a related but less important note: the formatting of rules might be
improved if was done like triggers are:

-- status quo
CREATE OR REPLACE RULE on_delete AS
     ON DELETE TO test DO INSTEAD  DELETE FROM test2
   WHERE test2.id = old.id;

-- proposal
CREATE OR REPLACE RULE on_delete AS
   ON DELETE
   TO test
   DO INSTEAD
   DELETE FROM test2
    WHERE test2.id = old.id;
