I've never said it was always a good idea. But killing correctly
running queries isn't always a good idea either. I'm interested in
using HS for running read-only replicas for load balancing. It would
pretty sad if queries dispatched to a read-only replica received a
spurious unpredictable errors for reasons the application programmer
cannot control.
I'll look at the buffer pin deadlock problem again, but I didn't
realize the situation was so dire. And what were the downsides of the
"stop gap"?
