   Move PartitionPruneInfo out of plan nodes into PlannedStmt

I think the attached is the correct fix.  I also wonder if it's worth
an isolation test to exercise this code.

Thanks for the patch, David, and for the report, Fei.  I indeed forgot
to update EvalPlanQualStart() in that commit.

I agree about adding an isolation test, which I have done in the
attached updated patch.

Thanks David and Amit for the patch. It looks OK to me, and isolation

testing confirms the issue. Also, should s1ppx and s2ppx in the case be

renamed to s4ppx and s5ppx?
