I noticed a couple of small issues for "Fix snapshot export and import
to work properly on a snapshot taken during recovery":

* The release notes should credit Bertrand Drouvot as an additional
author of the fix.

* Seems worth pointing out that this problem is associated with
running pg_dump with multiple jobs (--jobs=N) on a standby [1]. It
might also be worth mentioning that it requires the subxact cache on
the primary to overflow.

I am 100% sure that this bug has real world relevance (unlike all of
the other corruption bugs I worked on for this release). It hit at
least a handful of users, causing alarming misbehavior on affected
standbys. That's why I'm being particular about how it gets presented.
