Agreed. Importantly, we won't have painted ourselves into a corner where we cannot add it later, now that RETURNING projects updates tuples, too (V1.5 established that). I'm pretty confident that it would be a mistake to try and make the inner "excluded" and "target" aliases visible, in any case, because of the annoying ambiguity it creates for the common, simple cases. I think it has to be a magic function, or something like that. I really hoped we'd be having a more technical, implementation level discussion at this point. Simon rightly emphasized the importance of getting the semantics right, and the importance of discussing that up front, but I'm concerned; that's almost all that has been discussed here so far, which is surely not balanced either. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
