15 ALTER GROUP changes the attributes of a user group. This is an obsolete
16 command, though still accepted for backwards compatibility, because
17 groups (and users too) have been superseded by the more general concept
18 of roles.
19
20 The first two variants add users to a group or remove them from a
21 group. (Any role can play the part of either a “user” or a “group” for
22 this purpose.) These variants are effectively equivalent to granting or
23 revoking membership in the role named as the “group”; so the preferred
24 way to do this is to use GRANT(7) or REVOKE(7).
25
26 The third variant changes the name of the group. This is exactly
27 equivalent to renaming the role with ALTER ROLE (ALTER_ROLE(7)).
28
30 group_name
31 The name of the group (role) to modify.
32
33 user_name
34 Users (roles) that are to be added to or removed from the group.
35 The users must already exist; ALTER GROUP does not create or drop
36 users.
37
38 new_name
39 The new name of the group.
40
42 Add users to a group:
43
44 ALTER GROUP staff ADD USER karl, john;
45
46 Remove a user from a group:
47
48 ALTER GROUP workers DROP USER beth;
49
51 There is no ALTER GROUP statement in the SQL standard.
52
54 GRANT(7), REVOKE(7), ALTER ROLE (ALTER_ROLE(7))
