あなたのエラーメッセージにこの行から判断：

ActiveRecord::StatementInvalid (PG::UndefinedTable: ERROR: relation "users" does not exist

移行はHerokuの上で正常に実行されなかったように私には思えます。

私は

heroku rake db:reset ('heroku run rake db:reset' if you're on cedar)

heroku rake db:migrate ('heroku run rake db:migrate' if you're on cedar)

を実行し、それは私を取得する場所を確認しようとするだろう。
