That makes way more sense.
I wonder if we can fix this problem by getting rid of the old support
routine #5, "options". It currently doesn't do anything, and I always
thought it was strange that it was added "for uniformity" with other
index AMs.
OTOH, one could argue that it's only a matter of time until somebody
needs to add another support routine to nbtree; why delay dealing with
the problem that you've highlighted? Right now I don't really have an
opinion on how best to address the problem.
