minor suggestion about rule syntax

Hello folks,

I would like suggest to add an ALSO keyword to the CREATE RULE
syntax, so as to allow :

CREATE RULE foo AS
ON DELETE TO bla
DO ALSO ...;

The semantics would not change wrt without this keyword, but it would make
it clearer that in this case the initial query is ALSO performed, as the
INSTEAD keywords which tells that it is not.
