ALTER GROUP(7)                     PostgreSQL 14.23 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       accepted for backwards compatibility, because groups (and users too) have been superseded by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.

       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.
