Hi

fresh update - I enhanced Value node by location field as Tom proposal.

Few more regress tests.

But I found significant issue, that needs bigger fix - Surafel, please, can you fix it.

It crash on 

SELECT 0 AS x1, 1 AS a, 0 AS x2, 2 AS b, 0 AS x3, -1 AS x3 

UNION ALL CORRESPONDING SELECT 4 AS b, 0 AS x4, 3 AS a, 0 AS x6, -1 AS x6 

UNION ALL CORRESPONDING SELECT 0 AS x8, 6 AS b, -100 AS x9;

I'll mark this patch as waiting on author
