Updateable VIEWS and the manual

Hi,

I just noticed the following statement in the CREATE VIEW documentation (9.2
and 9.1):

Currently, views are read only: the system will not allow an insert,
update, or delete on a view. You can get the effect of an updatable view
by
creating rules that rewrite inserts, etc. on the view into appropriate
actions
on other tables. For more information see CREATE RULE.

Wouldn't it make more sense to refer to INSTEAD OF triggers?

My understanding was that an INSTEAD OF trigger was preferred over a rule
nowadays.

yup.

Done, thanks for pointing it out.
