Updated:

 . remove from explain analyze those tests which would display sort
   Memory/Disk.  Oops.
 . fix issue with the first patch showing zero "tuples" memory for some
   grouping sets.
 . reclassify memory as "tuples" if it has to do with "members".  So hashtable
   size is now redundant with nbuckets (if you know
   sizeof(TupleHashEntryData));
