如何在postgres中删除超级用户

Question

我创建了一个具有超级用户角色的新用户rentdb，当我尝试删除时，我会得到它与某些pg函数有关的依赖关系。 有没有办法可以完全删除rentdb。

  postgres-# \du
                                   List of roles
 Role name |                         Attributes                         | Member of 
-----------+------------------------------------------------------------+-----------
 postgres  | Superuser, Create role, Create DB, Replication, Bypass RLS | {}
 rentdb    | Superuser                                                  | {}

Answer 1

As documented in the manual您可以{}为用户拥有的drop everything：

drop owned by rentdb cascade;

或assign将这些对象发送给其他用户：

reassign owned by rentdb to postgres;
