DESCRIPTION

   The REVOKE command revokes previously granted privileges from one or
   more roles. The key word PUBLIC refers to the implicitly defined group
   of all roles.

   See the description of the GRANT(7) command for the meaning of the
   privilege types.

   Note that any particular role will have the sum of privileges granted
   directly to it, privileges granted to any role it is presently a member
   of, and privileges granted to PUBLIC. Thus, for example, revoking
   SELECT privilege from PUBLIC does not necessarily mean that all roles
   have lost SELECT privilege on the object: those who have it granted
   directly or via another role will still have it. Similarly, revoking
   SELECT from a user might not prevent that user from using SELECT if
   PUBLIC or another membership role still has SELECT rights.

   If GRANT OPTION FOR is specified, only the grant option for the
   privilege is revoked, not the privilege itself. Otherwise, both the
   privilege and the grant option are revoked.

   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; if it is
   not, 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 might effectively keep the privilege if it was also
   granted through other users.

   When revoking privileges on a table, the corresponding column
   privileges (if any) are automatically revoked on each column of the
   table, as well. On the other hand, if a role has been granted
   privileges on a table, then revoking the same privileges from
   individual columns will have no effect.

   When revoking membership in a role, GRANT OPTION is instead called
   ADMIN OPTION, but the behavior is similar. Note also that this form of
   the command does not allow the noise word GROUP.

NOTES

   Use psql(1)'s \dp command to display the privileges granted on existing
   tables and columns. See GRANT(7) for information about the format. For
   non-table objects there are other \d commands that can display their
   privileges.

   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 in turn revoked from user C. For another example, if
   both A and B have granted the same privilege to C, A can revoke his own
   grant but not B's grant, so C will still effectively have the
   privilege.

   When a non-owner of an object attempts to REVOKE privileges on the
   object, the command will fail outright if the user has no privileges
   whatsoever on the object. As long as some privilege is available, the
   command will proceed, but it will revoke only those privileges for
   which the user has grant options. The REVOKE ALL PRIVILEGES forms will
   issue a warning message if no grant options are held, while the other
   forms will issue a warning if grant options for any of the privileges
   specifically named in the command are not held. (In principle these
   statements apply to the object owner as well, but since the owner is
   always treated as holding all grant options, the cases can never
   occur.)

   If a superuser chooses to issue a GRANT or REVOKE command, the command
   is performed as though it were issued by the owner of the affected
   object. Since all privileges ultimately come from the object owner
   (possibly indirectly via chains of grant options), it is possible for a
   superuser to revoke all privileges, but this might require use of
   CASCADE as stated above.

   REVOKE can also be done by a role that is not the owner of the affected
   object, but is a member of the role that owns the object, or is a
   member of a role that holds privileges WITH GRANT OPTION on the object.
   In this case the command is performed as though it were issued by the
   containing role that actually owns the object or holds the privileges
   WITH GRANT OPTION. For example, if table t1 is owned by role g1, of
   which role u1 is a member, then u1 can revoke privileges on t1 that are
   recorded as being granted by g1. This would include grants made by u1
   as well as by other members of role g1.

   If the role executing REVOKE holds privileges indirectly via more than
   one role membership path, it is unspecified which containing role will
   be used to perform the command. In such cases it is best practice to
   use SET ROLE to become the specific role you want to do the REVOKE as.
   Failure to do so might lead to revoking privileges other than the ones
   you intended, or not revoking anything at all.

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;

   Note that this actually means "revoke all privileges that I granted".

   Revoke membership in role admins from user joe:

       REVOKE admins FROM joe;

COMPATIBILITY

   The compatibility notes of the GRANT(7) command apply analogously to
   REVOKE. The keyword RESTRICT or CASCADE is required according to the
   standard, but PostgreSQL assumes RESTRICT by default.
