Yeah, loss of the causality relationship is the main thing that's bugging me too. If we sorted by OID then in most cases the objects would be listed in creation order, which would likely also have something to do with the dependency order; but it would be different in the same cases that are most likely to be confusing :-( I do not buy Andres' concern about parallelism breaking the test results. We only ever drop objects created in the same test, so their OID ordering would be the same (ie creation order) in every case unless an OID wraparound occurred mid-test, which isn't a situation I feel a need to worry about for this purpose. However, possible loss of user friendliness *is* a valid concern here. Anyway, we don't need a design for this today. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
