The built-in data types have hand-assigned OIDs, as depicted in src/include/catalog/pg_type.h. While those aren't quite guaranteed-frozen, we've never changed one that I can recall, and are not very likely to in the future. However, any type that's not built-in has an OID that will vary across databases. As a rule of thumb, you could assume that any OID under 10000 is hand-assigned and won't change. 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
