If you can provide a reproducible example of a deadlock induced by
REINDEX + VACUUM, that would be interesting.

posting to -hackers about it, but I've never seen it occur in a
real-world situation...)

Yeah, I wouldn't be surprised if there is some room for optimizing the
locks that are acquired by REINDEX.
