Uh ... recommended by whom?  pg_statistic has exactly the same reliability
guarantees as the rest of the system catalogs.

I don't deny that there might be cases where this is worth doing, but
it does not seem so likely that it should be part of one's standard
checklist.  Much less something that we should expend a great deal
of effort to automate.
