New in v2.0: The REVOKE <roles> statement lets you revoke a role or user's membership to a role.
Synopsis
Required Privileges
The user revoking role membership must be a role admin (i.e., members with the ADMIN OPTION) or a superuser (i.e., a member of the admin role).
Considerations
- The
rootuser cannot be revoked from theadminrole.
