------------------------------------------------------------------
[~jamestaylor]The temp schema is to work with Aggregate projection to replace
rowProjector. All UnionAllIT tests passed with Plan Order By and Limit.
Wrapping another Select over current Union All selects we need to specify a
table. A dummy table or Null table did not work since parser needs a real table
to resolve column information etc. I have to say if we have taken my very early
approach of passing down rowProjector, we can simplify the approach quite bit.
