英文:
Do I need to REVOKE permissions when a table is dropped
问题
需要在降级迁移中添加以下内容吗？
```sql
REVOKE SELECT, INSERT, DELETE ON table1 FROM user;
英文:
As part of a migration I create a table and grant permissions to a user. Do I need to REVOKE the permissions on my downgrade migration which already drops the table?
--- up.sql
CREATE TABLE IF NOT EXISTS table1 (id int primary key);
GRANT SELECT, INSERT, DELETE ON TABLE table1 TO user1;
--- down.sql
DROP TABLE IF EXISTS table1;
Do I need to add the following or is it implicit?
REVOKE SELECT, INSERT, DELETE ON table1 FROM user;

如果您丢弃一个对象，它的所有权限也会丢失。这是因为权限存储在对象本身上：在表的情况下，权限存储在pg_class表的relacl列中（其中存储了所有表）。
英文:
If you drop an object, all its privileges are also gone. That is because privileges are stored on the object itself: in the case of a table, the privileges are stored in the relacl column of the pg_class table (where all tables are stored).
