ALTER GROUP(7) PostgreSQL 16.7 Documentation ALTER GROUP(7)
NAME
ALTER_GROUP - change role name or membership
SYNOPSIS
ALTER GROUP role_specification ADD USER user_name [, ... ]
ALTER GROUP role_specification DROP USER user_name [, ... ]
where role_specification can be:
role_name
| CURRENT_ROLE
| CURRENT_USER
| SESSION_USER
ALTER GROUP group_name RENAME TO new_name
DESCRIPTION
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groups (and users too) have been superseded by the more general concept
of roles.
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 or REVOKE. Note that GRANT and REVOKE
have additional options which are not available with this command, such
as the ability to grant and revoke ADMIN OPTION, and the ability to
specify the grantor.
The third variant changes the name of the group. This is exactly
equivalent to renaming the role with ALTER ROLE.
PARAMETERS
group_name
The name of the group (role) to modify.
user_name
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
users.
new_name
The new name of the group.
EXAMPLES
Add users to a group:
ALTER GROUP staff ADD USER karl, john;
Remove a user from a group:
ALTER GROUP workers DROP USER beth;
COMPATIBILITY
There is no ALTER GROUP statement in the SQL standard.
