The reviewer has to review two different set of changes to the same
portion of the code. That just doubles the work. I didn't find that
simplifying review. As I have suggested earlier, let's define
get_default_partition_oid() only once, mostly in or before 0003 patch.
Having it in a separate patch would allow you to change its
implementation if needed.
