That's an interesting point, do streaming replication connections
consume superuser_reserved_connections slots? How should
superuser_reserved_connections be set?

Hmm, that makes the HOT STANDBY notice after that section look weird:

Do we need that notice? Maybe just move that sentence to the "STANDBY
SERVER PARAMETERS" section.
I just committed a patch to move around the high-availability sections a
bit. That caused conflicts with this patch, so I picked the changes from
the patch and applied them over the new layout, and I also did a lot of
other editing. So, I committed most parts of this patch (except the
above), with a lot of changes to fix the bit-rot, and also other editing
to my liking. I hope I made it better not worse.
