This thread has stalled for a couple of weeks, so I have gone back to
it.  Testing on a tmpfs I am not seeing a difference if performance
for any of the approaches discussed.  At the end, as I am the one
behind the introduction of pg_pwrite_zeros(), I have applied v3 after
switches the size and offset parameters to be the same way as in v4.
