AWS DMSを使用してHeroku PostgreSQLデータベースからAWS RDS PostgreSQLインスタンスにデータをコピーしてレプリケートしようとしていますが、 （以下の情報を参照）。AWSデータマイグレーションサービス（DMS）を使用してHeroku PostgreSQLからAWS RDSに移行する

HerokuのPostgreSQLのユーザがスーパーユーザではないか、レプリケーションの役割を持っているが、私はそれを2日前に、同じソース・データベースとの実験を行ったとしました：
DMSログでは、私は次のようなメッセージを見ることができます正しく動作しました（実験を停止して、より大きなRDSインスタンスターゲットを作成しました）。私は今回の設定で何かを忘れていると思う。
- 出典：HerokuのPostgreSQLの標準-2（9.5.8）
- ターゲット：AWS RDSのPostgreSQL（9.6.3）rds.logical_replication = 1つの
- DMSとSA-東-1領域で：インスタンス私たち-東-1の領域
