REVOKE PRIVILEGE

REVOKE revokes privileges from a database object. The PUBLIC pseudo-role can be used to indicate that the privileges should be revoked from all roles (including roles that might not exist yet).

Field Use
object_name The object that privileges are being revoked from.
ALL object_type IN SCHEMA schema_name The privilege will be revoked from all objects of object_type in schema_name.
ALL object_type IN DATABASE database_name The privilege will be revoked from all objects of object_type in database_name.
ALL object_type The privilege will be revoked from all objects of object_type, excluding system objects.
role_name The role name that is losing privileges. Use the PUBLIC pseudo-role to revoke privileges from all roles.
SELECT Allows reading rows from an object. The abbreviation for this privilege is ‘r’ (read).
INSERT Allows inserting into an object. The abbreviation for this privilege is ‘a’ (append).
UPDATE Allows updating an object (requires SELECT if a read is necessary). The abbreviation for this privilege is ‘w’ (write).
DELETE Allows deleting from an object (requires SELECT if a read is necessary). The abbreviation for this privilege is ’d'.
CREATE Allows creating a new object within another object. The abbreviation for this privilege is ‘C’.
USAGE Allows using an object or looking up members of an object. The abbreviation for this privilege is ‘U’.
CREATEROLE Allows creating, altering, deleting roles and the ability to grant and revoke role membership. This privilege is very powerful. It allows roles to grant and revoke membership in other roles, even if it doesn’t have explicit membership in those roles. As a consequence, any role with this privilege can obtain the privileges of any other role in the system. The abbreviation for this privilege is ‘R’ (Role).
CREATEDB Allows creating databases. The abbreviation for this privilege is ‘B’ (dataBase).
CREATECLUSTER Allows creating clusters. The abbreviation for this privilege is ‘N’ (compute Node).
ALL PRIVILEGES All applicable privileges for the provided object type.

Details

The following tables describes which privileges are applicable to which objects:

NOTE: For PostgreSQL compatibility reasons, you must specify TABLE as the object type for sources, views, and materialized views, or omit the object type.
Object type All privileges
SYSTEM RBN
DATABASE UC
SCHEMA UC
TABLE arwd
(VIEW) r
(MATERIALIZED VIEW) r
INDEX
TYPE U
(SOURCE) r
SINK
CONNECTION U
SECRET U
CLUSTER UC

Unlike PostgreSQL, UPDATE and DELETE always require SELECT privileges on the object being updated.

Compatibility

For PostgreSQL compatibility reasons, you must specify TABLE as the object type for sources, views, and materialized views, or omit the object type.

Examples

REVOKE SELECT ON mv FROM joe, mike;

REVOKE USAGE, CREATE ON DATABASE materialize FROM joe;

REVOKE ALL ON CLUSTER dev FROM joe;

REVOKE CREATEDB ON SYSTEM FROM joe;

Privileges

The privileges required to execute this statement are:

  • Ownership of affected objects.
  • USAGE privileges on the containing database if the affected object is a schema.
  • USAGE privileges on the containing schema if the affected object is namespaced by a schema.
  • superuser status if the privilege is a system privilege.
