Postgresql 为什么可以'；我不能删除accounts表的外键约束吗？

我有一个

accounts

表，该表具有此

外键

约束：

TABLE "edits" CONSTRAINT "edits_account_id_fkey1" FOREIGN KEY (account_id) REFERENCES accounts(id) ON DELETE CASCADE

我想删除此约束，但每次尝试执行以下命令时：

ALTER TABLE accounts DROP CONSTRAINT edits_account_id_fkey1;

我得到这个错误：

ERROR:  constraint "edits_account_id_fkey1" of relation "accounts" does not exist

它显然存在。我正在使用

\d accounts

命令查看它。为什么会这样

      etc...... etc......

约束放置在表

编辑

，但您正在更改表

帐户

。将查询中的

accounts

更改为

edits

，然后它就会工作。

我在该输出中没有看到名为

edits\u account\u id\u fkey1

的约束。
