I believe the intended advantage of the current system is that if you specify multiple operations in a single ALTER TABLE command, you only do one scan rather than having a second scan per operation. If that's currently working, we probably don't want to make it stop working. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
