But I think the real problem with Ron's proposal is that it presumes there is a one-size-fits-all notion of "system schema". As a counterexample, for some maintenance activities (such as vacuuming) you might wish to process pg_catalog. What I'd suggest as an improvement that could be implemented immediately is to wrap the checks in a user-defined function like "is_system_schema(nspname name)". regards, tom lane
