Re: Deadlock detected after pg_repack receives SIGINT

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
