# Creating, altering, and deleting groups
<a name="r_Groups-creating-altering-and-deleting-groups"></a>

Only a superuser can create, alter, or drop groups.

You can perform the following actions:
+ To create a group, use the [CREATE GROUP](r_CREATE_GROUP.md) command.
+ To add users to or remove users from an existing group, use the [ALTER GROUP](r_ALTER_GROUP.md) command.
+ To delete a group, use the [DROP GROUP](r_DROP_GROUP.md) command. This command only drops the group, not its member users.
