Thanks Rajkumar for testing.

Here's a v2 of the delta patch that should fix both of these test
failures. As I mentioned in my last reply, my delta patch fixed what
I think were problems in Nitin's v3 patch but were not complete by
themselves. Especially, I hadn't bothered to investigate various /*
TODO: handle multi-column list partitioning */ sites to deal with my
own changes.

In the attached updated version, I've dealt with some of those such
that at least the existing cases exercising partition pruning and
partition wise joins now pass.

I thought about sending a v4 of the main patch with my proposed
changes so far integrated, but decided to just post a delta_v2 for
now.
