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?
