The key word PUBLIC refers to the implicitly defined group of all users. Note that any particular user will have the sum of privileges granted directly to him, privileges granted to any group he is presently a member of, and privileges granted to PUBLIC. Thus, for example, revoking SELECT privilege from PUBLIC does not necessarily mean that all users have lost SELECT privilege on the object: those who have it granted directly or via a group will still have it. See the description of the command for the meaning of the privilege types. If GRANT OPTION FOR is specified, only the grant option for the privilege is revoked, not the privilege itself. If a user holds a privilege with grant option and has granted it to other users then the privileges held by those other users are called dependent privileges. If the privilege or the grant option held by the first user is being revoked and dependent privileges exist, those dependent privileges are also revoked if CASCADE is specified, else the revoke action will fail. This recursive revocation only affects privileges that were granted through a chain of users that is traceable to the user that is the subject of this REVOKE command. Thus, the affected users may effectively keep the privilege if it was also granted through other users. Notes Use 's \z command to display the privileges granted on existing objects. See also for information about the format. A user can only revoke privileges that were granted directly by that user. If, for example, user A has granted a privilege with grant option to user B, and user B has in turned granted it to user C, then user A cannot revoke the privilege directly from C. Instead, user A could revoke the grant option from user B and use the CASCADE option so that the privilege is automatically revoked from user C. Examples Revoke insert privilege for the public on table films: REVOKE INSERT ON films FROM PUBLIC; Revoke all privileges from user manuel on view kinds: REVOKE ALL PRIVILEGES ON kinds FROM manuel; Compatibility SQL92 The compatibility notes of the command apply analogously to REVOKE. The syntax summary is: REVOKE [ GRANT OPTION FOR ] { SELECT | INSERT | UPDATE | DELETE | REFERENCES } ON object [ ( column [, ...] ) ] FROM { PUBLIC | username [, ...] } { RESTRICT | CASCADE } One of RESTRICT or CASCADE is required.
