And what's wrong with that? Essentially this comes from the conclusion
that 10/8 is less than 10.0.0.0/32, which I have no problem with.

That would break the rule that network part is major sort key and host
part is minor sort key, which I think is useful behavior.

It is?
regression=# select '10.1.2.0/24'::cidr < '10.0.0.0/8'::cidr;?column?
