I think this is for new todo items:create insert, update and delete rules for simple one table viewschange elog for
complexview ins|upd|del to "cannot {ins|upd|del}
 
[into|from] complex view without an on {ins|upd|del} rule"add the functionality for "with check option" clause of
createview

The second of these three items is done already (in the rewriter,
not the executor):

regression=# create view vv1 as select * from int4_tbl;
CREATE
regression=# insert into vv1 values (33);
ERROR:  Cannot insert into a view without an appropriate rule
        regards, tom lane

TODO updated.
