Right now, the partition_bound_accepts_nulls() has two callers viz.
check_new_partition_bound() and get_partition_for_tuple(). Both of
those callers are calling it only in case of LIST partition. So,
having null_index uninitialized in PartitionBoundInfoData is not a
problem. But in general, we shouldn't leave a field uninitialized in
that structure, so +1 for the patch.
