I really don't think it does, or if it does then the code is already
broken as it is now.
As the code is today, we obtain the locks well after the plan is
locked in. The only difference with this patch is that we do the
locking on routing tuples to the partition for the first time rather
than do them all at once when setting up the routing data structure.
