Thanks for the patch! Looks interesting.

On a first glance the whole concept of non-multicolumn index with included attributes seems...well, just difficult to
understand.
But I expect for SP-GiST this must be single key with multiple included attributes, right?
I couldn't find a test that checks impossibility of on 2-column SP-GiST, only few asserts about it. Is this checked
somewhereelse? 

Thanks!

Best regards, Andrey Borodin.
