Hm.  Maybe we should just document that the option requires SELECT
privileges on pg_statistic and pg_statistic_ext_data (which are restricted
to superusers by default).  I suspect we have relatively limited
opportunities for tuning the query, and I'd like to avoid invasive changes
to v18 at this point.
