If there's enough uniformity in all of those places to make that
feasible, it certainly seems wise to do it that way.  I don't know if
that's the case, though - e.g. maybe some callers want to exit and
others do not.  pg_resetxlog wants to exit; pg_archivecleanup and
pg_standby most likely want to print an error and carry on.
