I also think that we could have better conventional regression test

I tried to minimize Michael's test case and add it to patch.

- if (ItemPointerIsValid(leafhikey))

+ if (ItemPointerGetBlockNumberNoCheck(leafhikey) != InvalidBlockNumber)

Should we use BTreeInnerTupleGetDownLink() as soon as we use

BTreeInnerTupleSetDownLink() for setting this?

Or even invent BTreeInnerTupleDownLinkIsValid() macro?
