I'm not sure I understand. When the concurrency issues in writeable CTEs get fixed, they could become a mechanism for doing what you describe, but I suspect there would be significant work involved in harnessing them to that task. They'll be pretty nice even without the automated view stuff, though :) Cheers, David. -- David Fetter <david@fetter.org> http://fetter.org/ Phone: +1 415 235 3778 AIM: dfetter666 Yahoo!: dfetter Skype: davidfetter XMPP: david.fetter@gmail.com iCal: webcal://www.tripit.com/feed/ical/people/david74/tripit.ics Remember to vote!
