 This sample shows how to get a [n8n](https://n8n.io/) app up using PostgreSQL as a database and running with Defang. We based it in part on the [original sample](https://github.com/n8n-io/n8n-hosting/tree/main/docker-compose/withPostgres) from the n8n team, but we have adapted it to be consistent with the way our other samples are configured.
