Yes, I remember your comments:
Keep in mind that 99% of the excuse for people to want to use SIGTERM is
that the backend isn't responding to SIGINT. If you've fixed things so
that SIGTERM cannot get them out of any situation that SIGINT doesn't
get them out of, I don't think it's a step forward.
[shrug...] They can do that now, most of the time. What this is about
is dealing with corner cases, and in that respect what your proposal
will do is replace soluble problems with insoluble ones. But I suppose
I can't stop you if you're insistent.
I need more than one person to tell me it is a bad idea because I think
it is a good idea.
If we tell people SIGTERM is not safe to use then why is making it safe
worse. And if it is safe, we can just add a function to enable SIGTERM
to the backend without doing the query cancel longjump().
