still be very valuable and easy to implement in my opinion (not for me

We still can't afford to log each and every statement as we have too
many and we don't want to afford more disk performance/space. Therefore
we log only statements slower than 50ms.
But for analyzing usage patterns it would be very nice to have this
combined with a sample_rate for logging.
logging_sample_rate = n
So each n-th statement will get logged regardless of execution time.
What do you think?
