With a precisely equal level of respect, that's a load of bunk. As has been discussed here many times in the past, those changes broke many applications that were just fine. Mine included, EnterpriseDB's included. It was designed to maximize rather than minimize breakage in ways that were completely unnecessary, and every time anyone dares to argue that the change was less than perfect in every respect, the reponses evince a level of dubiousness normally reserved for the parole hearings of convicted murderers. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
