I was under the impression the factor was 67% for data loaded on the
leading-edge of an index, and 50% for other INSERTs.
(backend/access/nbtree/nbtinsert.c)

Not sure, without checking, what CREATE INDEX and COPY do, but I'm
guessing it is similar?

Other RDBMS use a higher leading-edge/standard fill factor.

There are situations where I'd want to set it at 90%, or even 100%. If I
know the update rate is likely to be zero, then I'd like my indexes to
fit in 10-30% less memory and disk, please.

Or am I missing something?
