I'm a bit reluctant to whack postgresql.conf around in back-branches
because sometimes that makes funny things happen when somebody
upgrades, e.g. via RPM.  I don't remember exactly what happens but I
think typically either the new file overwrites the existing file which
gets moved to something like postgresql.conf.rpmsave or the new file
is written into postgresql.conf.rpmnew instead of the original
location.  I don't think it's worth making stuff like that happen for
the sake of a comment.
