We have seen reports of similar things in situations where the real
problem was that the lock table had gotten too big --- is it possible
that you had something going on in parallel that would have acquired
lots of locks? If so, raising max_locks_per_transaction should avoid
the problem.
I'll look at whether we couldn't downgrade the failure to something
less than a PANIC, too ...
