I've noticed that on some platforms, it works better to attach gdb to the
backend process before you load the extension, but on others, it works
better to attach afterwards. You might try the opposite procedure from
whatever you were doing. Other than that, it's mostly Just Worked for
me on any remotely modern platform. Be sure both the backend and the
extension are compiled with -g, of course.
