Hello.
Is it possible to somehow determine index's attribute number that is target
one for given scankey?
I've checked nbtree AM code and found no evidence of such an ability. I need
that, because I'm storing each indexed value only once in a form of index
tuple, consisting of only 1 attribute.
If that's not possible now, I'd like to add sk_index_attnum entry to the
ScanKeyData structure.
