commit 09c1c6ab4bc5764dd69c53ccfd43b2060b1fd090
Support INCLUDE'd columns in SP-GiST.
Not much to say here: does what it says on the tin.
We steal a previously-always-zero bit from the nextOffset
field of leaf index tuples in order to track whether there
is a nulls bitmap. Otherwise it works about like included
columns in other index types.
