> @Leon-WTF Is this ready for review?
@cgivre Not yet, I'm handling the EXCEPT case, it needs to remove the
duplicate records for probe side, I'm trying to add an Agg phase after setop
phase. The agg phase needs a flag to indicate that it needs to group by all
columns as the columns can not be known when doing the plan. Any suggestion on
this?
