Can I remove create table permission in postgresql 8.3?

Question

Using postgresql 8.3, I've created a read only user like this:

create role reportuser with login password 'secret';

and then granted select to all the tables this user needs to access.

but I see this user can create table x (... and insert/update/delete/drop the table.

Is there a way to remove create table permissions for this user on this database?

Answer 1

Yes. Revoke privileges from public schema.
