That's a really good point: if you follow this approach then you're creating fundamental conflicts for use of the feature in trigger functions or rules, which will necessarily have conflicting uses of those names. Yeah, we could define scoping rules such that there's an unambiguous interpretation, but then the user is just out of luck if he wants to reference the other definition. (This problem is probably actually worse if you implement with reserved words rather than aliases.) I'm thinking it would be better to invent some other notation for access to old-row values. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
