As for the cases such that NUMBER OF INDEX TUPLES < HEAP,
we know at least one of the cause. I have had a fix for it and would
commit it in a week or so(Currently my local branch is broken due
to configure tree change). But as for the cases such that NUMBER
OF INDEX TUPLES > HEAP,the cause seems to be not clear yet.
