Can't imagine putting anything related to external-database access
inside either the btree or hash AMs; it'd only make sense to handle
it at higher levels. It's barely conceivable that external access
would make sense as a specialized AM in its own right, but I don't
see managing external links exclusively within the indexes.
IOW, if we did need extra stuff in IndexTuples for external access,
we'd want to put it inside IndexTuple, not in a place where it could
only be seen by these AMs.
