I notice you put the prototype for get_hash_mem in nodeHash.h. This
would be fine if not for the fact that optimizer needs to call the
function too, which means now optimizer have to include executor headers
-- not a great thing. I'd move the prototype elsewhere to avoid this,
and I think miscadmin.h is a decent place for the prototype, next to
work_mem and m_w_m. It remains strange to have the function in executor
implementation, but I don't offhand see a better place, so maybe it's
okay where it is.

Other than that admittedly trivial complaint, I found nothing to
complain about in this patch.
