Maybe using the word "prohibit" makes it a bit clear? For example, In guc_tables.c: Prohibits access to non-system relations of specified kinds In doc: Set relation kinds of non-system relations to which access is prohibited. It takes a comma-separated list of relation kinds. Currently, the supported relation kinds are view and foreign-table. Regards, -- Masahiko Sawada Amazon Web Services: https://aws.amazon.com
