Hi Kevin,
my point was, that pg_repack deadlocked itself - I think it should be possible to guarantee deadlock-free behavior at least via advisory lock for operations of pg_repack itself (I understand it is not possible to guarantee this across more apps). If it is not true, I'd be glad to hear I'm wrong (really!).
Thanks,
Jiri

I would be very interesting in seeing a description of what locking
policy would guarantee deadlock-free behavior when run concurrently
with unknown software. If you have a link to a paper on the topic,
that would serve as well as a description here.
