Hmmm ... well, I can make a real-world case from my supported apps for
transaction/statement kills. But my support for session kills is just
hypothetical; any time I've had to kill off sessions, it's because I had to
shut the database down, and that's better done from the command line.
My web apps which need to manage the number of connections do it through their
connection pool.
So I would vote for Yes on SIGINT by XID, but No on SIGTERM by PID, if Tom
thinks there will be any significant support & troubleshooting involved for
the latter.
Unless, of course, someone can give us a real business case that they have
actually encountered in production.
