Yes. Best bet is to send them SIGINT, which will cause a clean query
cancel, and then they'll notice the client connection went away and
quit. More drastic measures might fool the postmaster into thinking
that a backend crashed, in which case it'll force a database-wide
restart, which you probably don't want.
