Hi! I'm one of the contributors to the repo. Just to clarify, our Docker image [0] only contains the latest version of Postgres (13) and the common extensions listed out here [1]. All the other features such as this [2] and this [3] are only available in the AWS EC2 or DO droplet images. We're currently updating the README to make that clearer :-)
Hi! I have just seen the commit on README.md, thank you for clarifying that :)
The image runs postgres directly indeed, but in the entrypoint, and then keeps it open using tail -f /dev/null. That, together with Ansible, makes it pretty peculiar image :)
