Honestly, I didn't touch that part of the patch. It's very interesting
though, I think it would be great to spend the rest of GSoC in it.

Off the top of my head though, there's many ways to go about DELETE
CASCADE. You could only delete the member of the referencing array or the
whole array. I think there's a lot of options the user might want to
consider and it's hard to generalize to DELETE CASCADE. Maybe new grammar
would be introduced here ?|
