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. -- nathan
