No. Unlike a typical transaction-based deadlock, I did not see a deadlock error come back - it just
seemed to wait indefinitely instead. So I'm not even sure anything will show up in the pg_locks
table. In any case, it will have to happen again before I can spelunk more, since I had to reset
everything because the system was dead and it was needed by others.
