Back in the v11 cycle, there was just not quite enough time to get the
MergeAppend run-time partition pruning patch in.

I've attached v24 of this patch.  The only changes done from v23 [1]
are to re-base the patch atop of current master. There's was a bit of
churn in the partition pruning and run-time pruning code last week.
I've re-aligned the new code to account for the work done there.

Looks solid. The only actual bug I see is that this doesn't honor the enable_partition_pruning GUC, but that's trivial to fix. So fixed that, reworded some of the comments a tiny bit, and committed. Thanks!
