Consider adding docker-compose.yml with Postgres, nginx, and uWSGI, making it possible to test the application with Debian stretch and PG 9.6, the status quo, and with Debian buster and PG 11; an experiment with this on an EC2 instance did not work, and it wasn't clear whether the issue was with the new Python version or a problem with the uwsgi-emperor.
This Docker arrangement would also be helpful in migrating other applications to buster.
