Are you reproducing the hang locally with my repro? Or do you have
your own repro? How are you testing pg_terminate_backend() and seeing
that the InterruptHoldoffCount is 1?

I noticed this problem occurring several times on PG16, but I didn't use your repro, and haven't found a way to reproduce the problem. Instead, I simply force the vacuum to enter a retry loop with the following code and found InterruptHoldoffCount is 1.

// if (unlikely(res == HEAPTUPLE_DEAD))
    goto retry;

Sorry, I should have mentioned that patch was against REL_14_STABLE.
Attached patch has the same functionality but should apply cleanly
against REL_15_STABLE.
 
Thanks, I would try that.
