Attached another version.
* tweaked EXPLAIN output some more
* rebased and cleaned up
* Added back the enable_hashagg_disk flag (defaulting to on). I've
gone back and forth on this, but it seems like a good idea to have it
there. So now there are a total of two GUCs: enable_hashagg_disk and
enable_groupingsets_hash_disk
Unless I (or someone else) finds something significant, this is close
to commit.
