Unless it changed in 8, you can't insert into or update a view. I don't know if rules will do the trick or not, to be honest I haven't figured out what they can and cannot do. As someone who used to use synonyms at the user/schema level in Oracle as a way to restrict access to a subset tables based on user-specific criteria (eg, restricting salesman 'X' to only his accounts in the customer master table), yes, synonyms would be nice. But if you really want them, become part of the development effort. -- Mike Nolan ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
