根据我所学到的，设置RLS应该很容易。但不知怎么的，我不能让它工作。请给我点光。谢谢
对于表student，我的策略如下：

CREATE POLICY "crud" ON "public"."student"
AS PERMISSIVE FOR ALL
TO public
USING ((id IN ( SELECT sb.student_id FROM student_branch sb WHERE (sb.branch_id = ( SELECT a.branch_id FROM admin a WHERE (a.id = '62bfcd1c-016c-416a-a155-388e766b411f'::uuid))))))
WITH CHECK ((id IN ( SELECT sb.student_id FROM student_branch sb WHERE (sb.branch_id = ( SELECT a.branch_id FROM admin a WHERE (a.id = '62bfcd1c-016c-416a-a155-388e766b411f'::uuid))))))

基本上是一个ID为62bfcd1c-016c-416a-a155-388e766b411f的管理员，假设branch_id = 1应该只看到表student_branch中branch_id = 1的学生，
但我得到的结果是空的。我试着运行下面的SQL语句，它工作正常，但策略没有得到强制执行。

select * from student where (id IN ( SELECT sb.student_id
       FROM student_branch sb
      WHERE (sb.branch_id = ( SELECT admin.branch_id
               FROM admin
              WHERE (admin.id = '62bfcd1c-016c-416a-a155-388e766b411f'::uuid)))))

1, Student 1
2, Student 2

管理员数据

id, name, branch_id
============
62bfcd1c-016c-416a-a155-388e766b411f, Admin 1, 1

学生分支数据

id, student_id, branch_id
======================
