To expand on the above and make a quick reference: 要扩展以上内容并快速参考：

• To make a user a SuperUser: ALTER USER username WITH SUPERUSER; 为了使用户成为超级用户： ALTER USER username WITH SUPERUSER;
• To make a user no longer a SuperUser: ALTER USER username WITH NOSUPERUSER; 使用户不再是超级用户： ALTER USER username WITH NOSUPERUSER;
• To just allow the user to create a database: ALTER USER username CREATEDB; 只是允许用户创建数据库： ALTER USER username CREATEDB;

You can also use CREATEROLE and CREATEUSER to allow a user privileges without making them a superuser. 您还可以使用CREATEROLE和CREATEUSER来允许用户权限，而不必使其成为超级用户。
