Yes, and for several releases before that too. You could reduce the
number of loops by increasing vacuum_mem (aka maintenance_work_mem).
One might speculate that you should be vacuuming this table more often,
btw ... when you've got something upwards of 19 million dead rows in
a 300MB table, that seems excessive.
