## Description

`ALTER GROUP` is used to add or remove users from a group. Only database superusers can use this command. Adding a user to a group does not create the user. Similarly, removing a user from a group does not drop the user itself.

Use SQL-CREATEGROUP-title to create a new group and SQL-DROPGROUP-title to remove a group.

## Usage

Add users to a group:

    ALTER GROUP staff ADD USER karl, john;

Remove a user from a group:

    ALTER GROUP workers DROP USER beth;
