OK, that's cleared, thanks, Now another question related to this. In 7.4.8 I have a schema with the following authorization: CREATE SCHEMA adeuxproductie AUTHORIZATION postgres; GRANT ALL ON SCHEMA adeuxproductie TO postgres; GRANT ALL ON SCHEMA adeuxproductie TO GROUP adeuxproductie; COMMENT ON SCHEMA adeuxproductie IS 'Standard production schema'; Now when I try to access the tables/views in the schema as a user that is NOT a member of the group adeuxproductie, I expect it to fail. However, access is granted as if there is no authorization specified. Is this a bug, or do I misunderstand something?
