Yipes. So we really want to do that only once.
AFAICS it is appropriate to move the sigsetjmp and setup_cancel_handler
calls in front of the per-line loop inside MainLoop --- can anyone see
a reason not to?
I'm inclined to treat this as an outright bug, not just a minor
performance issue, because it implies that a sufficiently long psql
script would probably crash a Windows machine.
