I wonder if we should have a different mode of operation that only
attempted the truncate (say VACUUM TRUNCATE), optionally being
non-conditional about obtaining the required lock. That said, I wonder
even more whether any such hacks are still needed after the visilibity
map that changed the landscape for vacuum so dramatically.
