Kevin said "It has become clear that the scope of problems being found
now exceed what I can be sure of being able to fix in time to make for
a stable release, in spite of the heroic efforts Thomas has been
putting in". I think it's clear that Kevin is willing to put in some
work. The issue is that he is unable to *guarantee* that he'll be able
to put in *sufficient* time, and in light of that concedes that it
might be best to revert and revisit for Postgres 11. He is being
cautious, and does not want to *risk* unduly holding up the release.

That was my understanding, at least.
