Here are the patches.
0001 Adds permission checks on the partitions before doing MERGE/SPLIT
0002 Skips copying extended statistics while creating new partitions
in MERGE/SPLIT

0001 looks quite simple and trivial for me.  I'm going to push it if
no objections.
For 0002 I'd like to hear some feedback on wordings used in docs and comments.
