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.
