DESCRIPTION

98       The REVOKE command revokes previously granted privileges from one or
99       more roles. The key word PUBLIC refers to the implicitly defined group
100       of all roles.
101
102       See the description of the GRANT(7) command for the meaning of the
103       privilege types.
104
105       Note that any particular role will have the sum of privileges granted
106       directly to it, privileges granted to any role it is presently a member
107       of, and privileges granted to PUBLIC. Thus, for example, revoking
108       SELECT privilege from PUBLIC does not necessarily mean that all roles
109       have lost SELECT privilege on the object: those who have it granted
110       directly or via another role will still have it. Similarly, revoking
111       SELECT from a user might not prevent that user from using SELECT if
112       PUBLIC or another membership role still has SELECT rights.
113
114       If GRANT OPTION FOR is specified, only the grant option for the
115       privilege is revoked, not the privilege itself. Otherwise, both the
116       privilege and the grant option are revoked.
117
118       If a user holds a privilege with grant option and has granted it to
119       other users then the privileges held by those other users are called
120       dependent privileges. If the privilege or the grant option held by the
121       first user is being revoked and dependent privileges exist, those
122       dependent privileges are also revoked if CASCADE is specified; if it is
123       not, the revoke action will fail. This recursive revocation only
124       affects privileges that were granted through a chain of users that is
125       traceable to the user that is the subject of this REVOKE command. Thus,
126       the affected users might effectively keep the privilege if it was also
127       granted through other users.
128
129       When revoking privileges on a table, the corresponding column
130       privileges (if any) are automatically revoked on each column of the
131       table, as well. On the other hand, if a role has been granted
132       privileges on a table, then revoking the same privileges from
133       individual columns will have no effect.
134
135       When revoking membership in a role, GRANT OPTION is instead called
136       ADMIN OPTION, but the behavior is similar. Note also that this form of
137       the command does not allow the noise word GROUP.
138

NOTES

140       Use psql(1)'s \dp command to display the privileges granted on existing
141       tables and columns. See GRANT(7) for information about the format. For
142       non-table objects there are other \d commands that can display their
143       privileges.
144
145       A user can only revoke privileges that were granted directly by that
146       user. If, for example, user A has granted a privilege with grant option
147       to user B, and user B has in turned granted it to user C, then user A
148       cannot revoke the privilege directly from C. Instead, user A could
149       revoke the grant option from user B and use the CASCADE option so that
150       the privilege is in turn revoked from user C. For another example, if
151       both A and B have granted the same privilege to C, A can revoke his own
152       grant but not B's grant, so C will still effectively have the
153       privilege.
154
155       When a non-owner of an object attempts to REVOKE privileges on the
156       object, the command will fail outright if the user has no privileges
157       whatsoever on the object. As long as some privilege is available, the
158       command will proceed, but it will revoke only those privileges for
159       which the user has grant options. The REVOKE ALL PRIVILEGES forms will
160       issue a warning message if no grant options are held, while the other
161       forms will issue a warning if grant options for any of the privileges
162       specifically named in the command are not held. (In principle these
163       statements apply to the object owner as well, but since the owner is
164       always treated as holding all grant options, the cases can never
165       occur.)
166
167       If a superuser chooses to issue a GRANT or REVOKE command, the command
168       is performed as though it were issued by the owner of the affected
169       object. Since all privileges ultimately come from the object owner
170       (possibly indirectly via chains of grant options), it is possible for a
171       superuser to revoke all privileges, but this might require use of
172       CASCADE as stated above.
173
174       REVOKE can also be done by a role that is not the owner of the affected
175       object, but is a member of the role that owns the object, or is a
176       member of a role that holds privileges WITH GRANT OPTION on the object.
177       In this case the command is performed as though it were issued by the
178       containing role that actually owns the object or holds the privileges
179       WITH GRANT OPTION. For example, if table t1 is owned by role g1, of
180       which role u1 is a member, then u1 can revoke privileges on t1 that are
181       recorded as being granted by g1. This would include grants made by u1
182       as well as by other members of role g1.
183
184       If the role executing REVOKE holds privileges indirectly via more than
185       one role membership path, it is unspecified which containing role will
186       be used to perform the command. In such cases it is best practice to
187       use SET ROLE to become the specific role you want to do the REVOKE as.
188       Failure to do so might lead to revoking privileges other than the ones
189       you intended, or not revoking anything at all.

EXAMPLES

192       Revoke insert privilege for the public on table films:
193
194           REVOKE INSERT ON films FROM PUBLIC;
195
196       Revoke all privileges from user manuel on view kinds:
197
198           REVOKE ALL PRIVILEGES ON kinds FROM manuel;
199
200       Note that this actually means “revoke all privileges that I granted”.
201
202       Revoke membership in role admins from user joe:
203
204           REVOKE admins FROM joe;
205

COMPATIBILITY

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