There's no reason that the server has to deal with a text file. I
completely agree that there must be a method to change settings even if
the database isn't running, but that method does not necessarily need to
be a text file. If we can come up with a standard API for reading and
writing config changes, we (or anyone else) can write any number of
tools to deal with the settings. And once we have an API, we can provide
a SQL interface on top of it.

Instead of focusing on exactly what the 'new postgresql.conf' is going
to look like we should focus on creating a clean configuration API. Once
we have that we can figure out what (if anything) we're doing with the
existing .conf, and what a new one (if it exists) might look like.
