  # (but mostly it's PostgREST that is going to be responsible for the bulk of the db traffic)
  # Having the database in a container is very convenient in development but in production you will
  # use a separate database instance, like Amazon RDS, i.e. in production this section will be
  # commented and in the .env file you will specify the ip of your separate database instance
