Also, I forgot to mention that let's not base this on buffer usage
patch for create index
(v10-0002-Allow-parallel-index-creation-to-accumulate-buff) because as
per recent discussion I am not sure about its usefulness.  I think we
can proceed with this patch without
v10-0002-Allow-parallel-index-creation-to-accumulate-buff as well.
