ALTER_GROUP - change role name or membership
ALTER GROUP group_name ADD USER user_name [, ... ]
ALTER GROUP group_name DROP USER user_name [, ... ]
ALTER GROUP group_name RENAME TO new_name
ALTER GROUP changes the attributes of a user group. This is an obsolete
command, though still accepted for backwards compatibility, because
groups (and users too) have been superseded by the more general concept
The first two variants add users to a group or remove them from a
group. (Any role can play the part of either a “user” or a “group” for
this purpose.) These variants are effectively equivalent to granting or
revoking membership in the role named as the “group”; so the preferred
way to do this is to use GRANT(7) or REVOKE(7).
The third variant changes the name of the group. This is exactly
equivalent to renaming the role with ALTER ROLE (ALTER_ROLE(7)).
The name of the group (role) to modify.
Users (roles) that are to be added to or removed from the group.
The users must already exist; ALTER GROUP does not create or drop
The new name of the group.
Add users to a group:
ALTER GROUP staff ADD USER karl, john;
Remove a user from a group:
ALTER GROUP workers DROP USER beth;
There is no ALTER GROUP statement in the SQL standard.
GRANT(7), REVOKE(7), ALTER ROLE (ALTER_ROLE(7))
