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;
