Dean Rasheed 5f2e179bd3 Support MERGE into updatable views. ... This allows the target relation of MERGE to be an auto-updatable or trigger-updatable view, and includes support for WITH CHECK OPTION, security barrier views, and security invoker views. A trigger-updatable view must have INSTEAD OF triggers for every type of action (INSERT, UPDATE, and DELETE) mentioned in the MERGE command. An auto-updatable view must not have any INSTEAD OF triggers. Mixing auto-update and trigger-update actions (i.e., having a partial set of INSTEAD OF triggers) is not supported. Rule-updatable views are also not supported, since there is no rewriter support for non-SELECT rules with MERGE operations. Dean Rasheed, reviewed by Jian He and Alvaro Herrera.
