Its certainly not useful to *me* in its current form. It would
produce way to much (usless) output. However if it were tied to
log_min_duration_statement so I get auto explains for long running
queries... That would be very useful indeed. Even if it has to
explain everything just to toss out the explain if it did not meet
log_min_duration_statement. Unless I missed something and thats
exactly what it does?
