If you pipe through it on the way to gzip, there is no increase in disk I/O over a straight gzip, and often an I/O savings. Benchmarks of the final version showed no measurable performance cost, even with full WAL files. It's not as convenient to use as what your patch does, but it's not all that hard either. There is also pglesslog, although we had pg_clearxlogtail working before we found the other, so we've never checked it out. Perhaps it does even better. -Kevin
