Is it possible to give multiple roles to the same user?
for example : 1. a general role "RoleA" for most users, for "grants and revokes" on certain tables and certain columns.
2. plus a role "Role_user" particular for each of them for its additional personal access with "grants" and "revokes" on other tables and columns.
Yes, though you can only grant privileges this way. Not revoke some.
