After moving all of this to a pristine postgresql.org based repo I see 
the same. My best guess at this point is that the permission hoops, that 
RDS and Aurora PostgreSQL are jumping through, was messing with this. 
But that has nothing to do with the actual topic.

So let's focus on the actual problem of running out of XIDs and memory 
while doing the upgrade involving millions of small large objects.
