Hi, It's postgres 15.4.
We want to give required privilege to certain users or roles and ensure
to not to provide any elevated privilege. I have below questions,
I would suggest spending some time here:
https://www.postgresql.org/docs/current/ddl-priv.html
It should answer many of your questions.
1)I am seeing in many places, we have "usage on schema" privilege given.
along with "grant select on <object_name> to <role1>" for the objects of
the schema (something as below). So I wanted to understand, what exact
privilege "grant usage on schema <schema1> to <role1>" will provide
which the "select on" privilege won't?
grant usage on schema <schema1> to <role1>;
grant select on schema1.tab1 to <role1>;
2)Additionally , when we are trying to give select privilege on "cron"
and "partman" schema to a role (something as below) , so that anybody
logging through that role would be able to see/fetch the data from the
tables inside cron and partman schema. its giving output '/no privileges
were granted for cron/partman/part_config/' message. And during
accessing that object from the cron/partman schema through that role, it
errors out with an access denied message. So I wanted to understand the
cause of this and how we should fix it , such that anybody logging in
through that role can see/fetch the data from the cron and partman
schema tables.
grant select on cron.job to <role1>;
grant select on cron.job_run_details to <role1>;
grant select on partman.part_config to <role1>;
