heroku run db:migrate を実行すると

StandardError: An error has occurred, this and all later migrations canceled:

PG::UndefinedTable: ERROR:  relation "users" does not exist
: ALTER TABLE "users" ADD "course" character varying

という感じでtableが存在しないいうことなので、先駆者たちの知恵を参考にマイグレーションファイルの名前を変更したのですが、ダメでした、、、

$ heroku pg:psqlをし、\dでテーブルを確認したところ

               List of relations

users テーブルどころか色々足りてないことがわかりましたが原因がわかりません

下記スキーマ
