The hardcoded fillfactor was 90% when building an index, and that's
still the default. However, when inserting to an existing index, the
fillfactor on the rightmost page was 2/3. It was changed to use the
user-configurable fillfactor, which now defaults to 90%.

Hmm. Now that I think of it, we might have the same bug in nbtsort.c.
I'll have a look...
