Better solution to the problem of labeling whole-row Datums that are
generated from subquery outputs: use the type info stored in the Var
itself. To avoid making ExecEvalVar and slot_getattr more complex
and slower, I split out the whole-row case into a separate ExecEval routine.

choose an index scan if your joining column's datatypes do not
match
