It would be nice to use this patch to test things that are important
but untested inside vacuumlazy.c, such as the rare
HEAPTUPLE_DEAD/tupgone case (grep for "Ordinarily, DEAD tuples would
have been removed by..."). Same is true of the closely related
heap_prepare_freeze_tuple()/heap_tuple_needs_freeze() code.
