But we have non-colliding generation technology for OIDs in system catalogs. We could try to reuse the idea in a UUID generator: grab one value, try to insert; if it fails generate a new one, lather, rinse, repeat. This would make uuidserial not quite as simple as SERIAL pseudotype, of course. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
