11

DESCRIPTION

22       ALTER GROUP changes the attributes of a user group. This is an obsolete
23       command, though still accepted for backwards compatibility, because
24       groups (and users too) have been superseded by the more general concept
25       of roles.
26
27       The first two variants add users to a group or remove them from a
28       group. (Any role can play the part of either a “user” or a “group” for
29       this purpose.) These variants are effectively equivalent to granting or
30       revoking membership in the role named as the “group”; so the preferred
31       way to do this is to use GRANT or REVOKE. Note that GRANT and REVOKE
32       have additional options which are not available with this command, such
33       as the ability to grant and revoke ADMIN OPTION, and the ability to
34       specify the grantor.
35
36       The third variant changes the name of the group. This is exactly
37       equivalent to renaming the role with ALTER ROLE.

PARAMETERS

40       group_name
41           The name of the group (role) to modify.
42
43       user_name
44           Users (roles) that are to be added to or removed from the group.
45           The users must already exist; ALTER GROUP does not create or drop
46           users.
47
48       new_name
49           The new name of the group.
50

EXAMPLES

52       Add users to a group:
53
54           ALTER GROUP staff ADD USER karl, john;
55
56       Remove a user from a group:
57
58           ALTER GROUP workers DROP USER beth;

COMPATIBILITY

61       There is no ALTER GROUP statement in the SQL standard.
