Don't know, maybe.
While looking for some places where tuple data might be
accessed directly inside of the buffers I've searched for
WriteBuffer() and friends. These are mostly used in the index
access methods and some other places where I expected them,
so index AM's have at least to be carefully visited when
implementing tuple split.
