In fact I just noticed that the number of stats tuples just climbed from 1236 to 2634. The ins/del counts are still zero. I ran analyze and the update counter went up only by 1232. For pg_autovacuum to vacuum this table I need (2*2634)+1000 = 6268 updates, which is never going to happen.
At least not before the number of tuples has climbed to beyond that count based on my experience to date!
