Hello, Andrey.
Thanks for your efforts.
> Patch on barrier seems too complicated to me right now. I’d propose to focus on KnowAssignedXidsNext patch: it’s
clean,simple and effective.
I'll extract it to the separated patch later.
> I’ve rebased the patch so that it does not depend on previous step. Please check out it’s current state, if you are
OKwith it - let’s mark the patch Ready for Committer. Just maybe slightly better commit message would make the patch
easierto understand.
Everything seems to be correct.
Best regards,
Michail.
