It's possible that that was true way back in Berkeley prehistory; there is no one around the project now that would remember (unless maybe Elein does). But the key points here are that critical catalogs like pg_class and pg_proc are per-database, which is a good thing for quite a number of reasons, and PG is sufficiently catalog-driven that it's literally impossible for the engine to do anything useful without having a set of those catalogs available. (Offhand, the only user-visible functionality I can think of that isn't catalog-dependent is the GUC parameters, ie SET/SHOW; and even within that there are some individual parameters that can't meaningfully be set without catalog access.) regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
