Hi Ilya,
Thanks for confirming the repros, and agreed on keeping the VACUUM case
best-effort.
> would you like to take them to a separate thread yourself?
Yes, I'll take P1 and P2 to their own thread and post them with a fix;
since they reach back to 14 that keeps this one small enough to
back-patch. I'll CC you.
Regards,
Manu
