My understanding is that the `:1` is added to make sure DFSchema uniqueness property is respected with regards to column names. I would argue that potentially we could move that differentiation to the `TableReference` qualification. In the repro above something like `alias.right.a` would be way better than `alias.a:1`. -- This is an automated message from the Apache Git Service.
