When the autovacuum system was introduced, we didn't have those columns.
But now it seems to make sense that a table with autoanalyze_count +
analyze_count = 0 should be a candidate for autovacuum even if the write
statistics are zero. Obviously, this would have the effect that a
pg_stat_reset() causes an immediate autovacuum for all tables, so maybe
it's not quite that simple.
