ALTER GROUP(7) PostgreSQL 12.3 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_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superseded by the more general concept of roles.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(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)).
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.
