Hi!

Last statement may be incorrect (if the logic is different).
Current user can attach another user's partition. If current user can 
change (attach) another user's partition, why can't he split the 
partition? After attach, partition is part of current user's table, and 
current user can change his own table. (Moreover, the owner of the new 
partitions is the same as the owner of the split partition.)
