There's already an interlock to prevent you from running it against a
live installation (it won't run if it sees a postmaster lock file).
That should also prevent an accidental run against a crashed installation
(presumably a lockfile will still be there). And if you run it against
a cleanly-shut-down installation, it's harmless because you don't need
the old xlog.
I don't think we need to be so paranoid as to insist that you saypg_resetxlog --yes-i-read-the-manual
before it will do anything.
