Subject: Effects of REVOKE SELECT ON ALL TABLES IN SCHEMA pg_catalog FROM PUBLIC
Date: Thu, 12 Sep 2024 05:41:03 +0200 (CEST)
Message-ID: <VisenaEmail.0.81936c517b2d9cfe.191e44de951@origo-test01.app.internal.visena.net> (raw)



Hei all.



Motivation: I have PowerBI users, with a separate ‘reporting’-role, accessing 
a database and I want to prevent them from listing all tables, users, databases 
and view-definitions (to not see the underlying query).



I'm evaluating this:
REVOKE SELECT ON ALL TABLES IN SCHEMA pg_catalog FROM PUBLIC; REVOKE SELECT ON 
ALL TABLES IN SCHEMA information_schema FROM PUBLIC;
Will this affect “normal behaviour”, ie. prevent the planner, or other 
internal mechanisms, from working properly for sessions logged in with the 
‘reporting’-role?



Thanks.
