为什么不能删除角色，因为某些对象依赖于它

Question

数据库 "mydb" 归角色 "mydb_owner" 所有。

用户 "currentuser" 尝试使用

从该数据库中删除角色 "roletodelete"

revoke all on all tables in schema public,firma1 from "roletodelete" cascade;
revoke all on all sequences in schema public,firma1 from "roletodelete" cascade;
revoke all on database mydb from "roletodelete" cascade;
revoke all on all functions in schema public,firma1 from "roletodelete" cascade;
revoke all on schema public,firma1 from "roletodelete" cascade;
revoke mydb_owner from "roletodelete" cascade;
ALTER DEFAULT PRIVILEGES IN SCHEMA public,firma1 revoke all ON TABLES from "roletodelete";
GRANT "roletodelete" TO "currentuser";
reassign owned by "roletodelete" to mydb_owner;
drop owned by "roletodelete";
drop role "roletodelete";

我运行它作为超级用户并获得了

    ERROR: role "roletodelete" cannot be dropped because some objects depend on it
DETAIL:  privileges for default privileges on new relations belonging to role currentuser in schema public
privileges for default privileges on new relations belonging to role currentuser schema firma1

如何创建 gua运行删除角色的脚本？

该脚本已经包含：

revoke all on schema public,firma1 from "roletodelete" cascade;

为什么 postgres 抱怨模式 public 的特权在被撤销后取决于此角色？如何解决这个问题？

我将他们的建议添加到上面的删除脚本中，但问题仍然存在。

遇到了同样的问题，用下面的办法解决了SQL

这应该在删除用户之前删除所有权限：

REASSIGN OWNED BY <user> TO <other-user>;

ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE GRANT OPTION FOR ALL PRIVILEGES ON TABLES FROM <user>;
ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE GRANT OPTION FOR ALL PRIVILEGES ON SEQUENCES FROM <user>;
ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE GRANT OPTION FOR ALL PRIVILEGES ON FUNCTIONS FROM <user>;
ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE GRANT OPTION FOR ALL PRIVILEGES ON ROUTINES FROM <user>;
ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE GRANT OPTION FOR ALL PRIVILEGES ON TYPES FROM <user>;

REVOKE GRANT OPTION FOR ALL PRIVILEGES ON SCHEMA <schema> FROM <user>;
REVOKE GRANT OPTION FOR ALL PRIVILEGES ON ALL TABLES IN SCHEMA <schema> FROM <user>;
REVOKE GRANT OPTION FOR ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA <schema> FROM <user>;
REVOKE GRANT OPTION FOR ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA <schema> FROM <user>;
REVOKE GRANT OPTION FOR ALL PRIVILEGES ON ALL PROCEDURES IN SCHEMA <schema> FROM <user>;
REVOKE GRANT OPTION FOR ALL PRIVILEGES ON ALL ROUTINES IN SCHEMA <schema> FROM <user>;

ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE ALL PRIVILEGES ON TABLES FROM <user>;
ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE ALL PRIVILEGES ON SEQUENCES FROM <user>;
ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE ALL PRIVILEGES ON FUNCTIONS FROM <user>;
ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE ALL PRIVILEGES ON ROUTINES FROM <user>;
ALTER DEFAULT PRIVILEGES IN SCHEMA <schema> REVOKE ALL PRIVILEGES ON TYPES FROM <user>;

REVOKE ALL PRIVILEGES ON SCHEMA <schema> FROM <user>;
REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA <schema> FROM <user>;
REVOKE ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA <schema> FROM <user>;
REVOKE ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA <schema> FROM <user>;
REVOKE ALL PRIVILEGES ON ALL PROCEDURES IN SCHEMA <schema> FROM <user>;
REVOKE ALL PRIVILEGES ON ALL ROUTINES IN SCHEMA <schema> FROM <user>;

DROP ROLE <user>;

这首先将所有数据库对象分配给另一个用户，撤销所有权限，包括默认权限，然后最终删除角色本身。
