Is it actually *running*, as in doing something, or is it just blocked?
I can't immediately think of any reason for some other process to have
a lock on a temp table that belongs to your process; but it seems
unlikely that ANALYZE would randomly take much longer than expected
unless something was preventing it from making progress.

Look into pg_locks and/or watch the backend with strace next time this
happens.
