Since there are no index scans, would it be safe to remove this one?
Yes. The block usage you're seeing there reflects the activity from
maintaining the index. But since it isn't ever being used for queries,
with zero scans and zero rows it's delivered to clients, it's not doing
you any good. Might as well reclaim your 1.7MB of disk space and reduce
overhead by removing it.
