+1. Keeping stuff like this in the documentation doesn't make those
platforms supported. What it does do is make it look like we're bad at
updating our documentation.

I strongly suspect that anyone who tried to use a modern PostgreSQL on
any of these platforms would find it quite an adventure, which is
fine, because if you're trying to use any of those platforms in 2022,
you are probably the sort of person who enjoys an adventure. But it
can't really be useful to list them in the documentation, and it's
unlikely that any of them "just work".
