Vacuum full will skew your results, unless you plan on running vacuum
full all the time. This is because you will always have some amount of
dead tuples in a table that has any update or delete activity. A regular
vacuum doesn't remove these tuples, it just marks them as available. So
over time, depending on how frequently a table is vacuumed, it will
settle down to a steady-state size that is greater than it's size after
a vacuum full.
