AFAIR, none of the index access methods except btree handle NULLs at
all --- they just ignore NULL values and don't store them in the index.
Feel free to improve on that ;-). The physical representation of index
tuples can handle NULLs, the problem is teaching the index logic where
they should go in the index.
