Hmmm ... it looks like REINDEX only grabs AccessShareLock on the target
relation, which seems very wrong. Hiroshi, doesn't it need to get a
stronger lock to prevent concurrent insertions? For that matter,
shouldn't the lock be obtained a lot earlier, to ensure the table isn't
dropped partway through? There's a lot of processing here that seems
to be executed while holding no lock at all :-(
