Yes; the point is that this is a pre-existing problem, not one being introduced with this patch. In SQL we don't have unsigned types, and we have historically chosen a type with the same width instead of one with enough width to represent all possible unsigned values. IMO this patch is doing the right thing; if in the future we want to change that decision, that's fine but it's a separate patch
