Sorry, I was imprecise. The view "pg_stats" doesn't have anything to do
with the stats collector; what I was interested in was the contents of
the "pg_stat_xxx" and "pg_statio_xxx" views. It'd be enough to check
pg_stat_all_indexes and pg_stat_all_tables, probably. Also, do you have
the 8.1 installation still available to get the comparable counts there?
