Comment (by pramsey):

 Yeah, this is #4523. It's not my fix here, it's the upgrade test PR from
 strk that I added along the way. It tests that ST_Union views are durable
 across upgrades, which I'm pretty sure they never were, because we always
 did drop/create on them. We only get away from that in Pg 12 which can do
 a create-or-replace. I'm commenting out strk's test.
