I'm really unwilling to get into that. For one thing, that would
absolutely positively break *all* use of EXPLAIN from un-fixed clients,
whether you were trying to stop early or not.

Doesn't matter, because that's not happening ;-) SIGINFO isn't
portable, and even if it were, a signal handler couldn't possibly
generate EXPLAIN output (remember those catalog accesses).
