Though next time you see a query which doesn't respond to

Hi. A long time has passed since you made that suggestion, but today we
stumbled again on a query that wouldn't be canceled. Not only does it
not respond to pg_cancel_backend(), it also doesn't respond to kill
-SIGTERM.
Interesting. If you attach gdb to the backend and run "backtrace",
what's the output?
If you strace the backend, what do you see?
