Re: postgres db permissions - Mailing list pgsql-general
None of the roles have permissions on the postgres database. At this point they don't have any permissions on any databases.
I have noted that "GRANT ALL ON SCHEMA public TO public" is granted on postgres.schemas.public. I am looking at this in pgadmin so excuse my nomenclature.
Is this what is allowing write access to the database?

Your problem is probably the "INHERIT" and
GRANT dbA TO bob;
GRANT dbA_ro TO bob;
GRANT dbB TO bob;
GRANT dbB_ro TO bob;
options. If any of the dbA's have the permission to CREATE tables (and I suspect they do), so will bob.GRANT dbA TO bob;
GRANT dbA_ro TO bob;
GRANT dbB TO bob;
GRANT dbB_ro TO bob;

Josh,
Via psql:
CREATE ROLE bob LOGIN
NOSUPERUSER INHERIT NOCREATEDB NOCREATEROLE NOREPLICATION;
GRANT dbA TO bob;
GRANT dbA_ro TO bob;
GRANT dbB TO bob;
GRANT dbB_ro TO bob;
dbA, dbA_ro, dbB, and dbB_ro are roles.
I have not created any database yet or assigned permissions to the roles.

How exactly did you add the users?
