Heh, I was about to update my node to that effect. The Transaction section in the DBI docs does mention turning on RaiseError. Strangely enough, it doesn't use the begin_work method, although I think it's a cleaner way of writing this pattern.

I looked at the code of begin_work, and it doesn't touch RaiseError. I suppose that makes sense in general, but I'd expect such a handy method to do that for me.
