Description

Columns with the same name can exist in key and value parts, and this works fine with KV views.
For non-binary RecordView, we could use some annotations as a workaround, but,
obviously, this will not work with the RecordBinary view, and no workaround is possible.

Let's prohibit columns with duplicate names.
