I'm back at looking into this again, after a rather exhausting week. I think I have a better grasp of what is going on in this code now, and it appears to me that we should change the locking so that active_pid is protected by ReplicationSlotControlLock instead of the slot's spinlock; but I haven't analyzed the idea fully yet and I don't have the patch done yet either. I'm going to report, hopefully with a fix committed this time, on Monday at 19:00 CLT.
