Well, first off, please confirm that killing off open client
transactions (you shouldn't even need to do a full postmaster restart)
makes the problem go away.
Beyond that, I have no advice except to be prepared to apply a debugger
next time. I believe we could fix the problem if we could examine the
situation VACUUM is seeing --- but it's so far not been possible to
do that, because the triggering conditions are so transient.
