But I think these outweigh the debugging benefit.

Well as Andrew said, we could also create postmaster start option that
defaults to don't save.

I think these days you'd simply use restart_after_crash = false. For
debugging I found that to be rather valuable.

That would have created an extended outage for this installation. I am not sure we can force that for something that should not happen in the first place (filling up the hard drive with dead files).
