Based on your review, I think the next step on $subject is for Teodor to
either commit gin_alone_cleanup-4.patch or to tell us what he'd like to see or
do before committing that patch.
While the failures during your crash recovery testing may not even be 9.6
regressions, they suggest the presence of serious bugs. At a minimum, the
community should confirm they are not 9.6 regressions before releasing 9.6. I
have added an open item to that effect.
