We need to expand this message later to support full fields of the star:
case class UnresolvedStar(target: Option[Seq[String]]) extends Star with Unevaluable {
which will be used to support Struct.

SELECT *in an explicit way by connect proto.Why are the changes needed?
Current proto uses empty project list for
SELECT *. However, this is an implicit way that it is hard to differentiatenot setandset but empty(the latter is invalid plan). For longer term proto compatibility, we should always use explicit fields for passing through information.Does this PR introduce any user-facing change?
No
