I don't think we need to go on about it at great length, but it seems
to me that it'd be reasonable to point out that (a) you'd be well
advised not to touch the file while the postmaster is up, and (b)
last setting wins. Those things are equally true of postgresql.conf
of course, but I don't recall whether they're already documented.
