Hmm.. So indeed there are very few HOT updates. What is the fillfactor
you are using for these tests ? If its much less than 100, the very
low percentage of HOT updates would make me guess that you are
updating one of the index columns. Otherwise at least the initial
updates until you fill up the free space should be HOT.
Thanks,
