Discourse を別の PostgreSQL (AWS RDS) を使用するように設定するために、以下のブログに従いました。

./launcher rebuild app を実行した後、以下のようなエラーが発生しました（画像添付）。

あまり詳しく見なくても、データベースサーバーは作成したが、discourseデータベースは作成しなかったということでしょうか？それとも、設定でデータベース名を提供しなかったということでしょうか？

DB設定はapp.ymlに以下のように記述されています。

env:
  DISCOURSE_DB_USERNAME: discourse
  DISCOURSE_DB_PASSWORD: "XXX"
  DISCOURSE_DB_HOST: xxx.rds.amazonaws.com
  DISCOURSE_DB_NAME: discourse

pgAdminを使用してこのDBに接続できます。Discourse用にこのDBで以下のコマンドを実行しました。

CREATE USER discourse PASSWORD 'XXX';
CREATE DATABASE discourse OWNER discourse;

CREATE EXTENSION hstore;
CREATE EXTENSION pg_trgm;

この問題について助けてください。
