Herokuにデプロイ、マイグレートしたらDB接続に問題が発生する

問題

Djangoでウェブアプリを開発し、Herokuにデプロイしました。そしてマイグレートするも以下のメッセージが表示されました。検索するとPostgreSQLに問題があるようです。何が問題なのかも見当がつきません。これまでデプロイしたことは何度かあるのですが、このようなエラーを見たのは初めてで戸惑っています。どうするべきでしょうか？

The above exception was the direct cause of the following exception:

試したこと

pg_ctl -D "C:\Program Files\PostgreSQL\13\data" start
pg_ctl -D "C:\Program Files\PostgreSQL\13\data" stop

再起動はされましたが、デプロイ先には特に影響はなく、同じ問題が出ています。
