The Railway dashboard's Database View only shows the default database (typically called railway) that was created when you deployed the Postgres service. Databases you create via DBeaver still exist and are accessible through DBeaver or any client connecting to your Postgres instance, but they won't appear in the dashboard's Data tab. If your application needs to use the new database, you'll need to update the DATABASE_URL variable in your app service to point to the new database name instead of the default one.
