The `/bin/bash` shebang points does not point to the correct path for bash in the container. Because of this, the initialization scripts will not run. Changing to `/usr/bin/env bash` fixes this problem.
Alternatively `/usr/bin/bash` would also work.
Docker Swarm Mode has been in severely declining usage and maintenance for years now. Meanwhile, Docker Compose has had quite a lot of changes (notably deprecating the `version:` field required by Swarm / forward compatibility). As a result, it no longer makes a ton of sense for us to prefer/suggest Swarm usages.
This changes all references to be `compose.yaml` (the upstream-preferred canonical filename: 9a9cc5d9c3/cli/options.go (L384-L385)) directly, leaving "swarm compatibility" as an exercise for the minority of readers who might still need/want it.
Unfortunately, this also means we need to remove all the play-with-docker links (since it only supports stack deploy via URL arguments, not compose), but my experience with that service is that it hasn't been terribly performant for a while, so I don't think this is a huge loss.
(There were also a few trailing references to the long-since-defunct Docker Machine project which have also been cleaned up.)
* Improve PGDATA warning about anonymous volumes
The people who most need to see this warning will struggle to
understand the meaning of the pre-existing language.
This updated warning:
- Refers to anonymous volumes by their correct name.
- Describes where the mystery mount is coming from.
- States the required behavior quite plainly, you must mount
at the correct location.

The sentence stated that no environment variables are required to use this image. However, the very first variable - POSTGRES_PASSWORD is stated as required. This is a direct contradiction. This change removes that contradiction and clarifies that the password is required.
