I think perhaps Optimizer / Executor would be more appropriate, since
these are not about hash indices but rather about hash joins.  I will
look at doing that.

Also I think the last item under Index / Hash is actually NOT done,
and belongs in the main index section rather than Index / Hash.

The first item in the Index / Hash section doesn't really look like a
TODO, or at the very least it's unclear what the action item is
supposed to be.
