ALTER [GROUP(7)](https://www.chedong.com/phpMan.php/man/GROUP/7/markdown)                     PostgreSQL 14.23 Documentation                     ALTER [GROUP(7)](https://www.chedong.com/phpMan.php/man/GROUP/7/markdown)



## 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       accepted for backwards compatibility, because groups (and users too) have been superseded by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.
