The reason they should be different is that (IMHO anyway) you don't want
the default behavior of SELECT * FROM ... to include pulling back the
entire contents of the blob.  Indeed, we *can't* have that be the
behavior, unless we want to go back to the proposal that started this
thread of making the entire system safe for multi-gigabyte datums.

It's certainly possible that the underlying implementation could be
just TOAST, but we need some other API at the SQL level.
