Not to beat a dead horse, but do we really want to force folks to be parsing logs for performance monitoring?
All of the really interesting DBA level information about checkpoints is now sitting in pg_stat_bgwriter. There really is no reason I'd expect this information to be part of normal performance monitoring setup; for me it has fit into troubleshooting and R&D.
When I'm talking about parsing logs in this context, it's for answering questions like "how does fsync time correlate with amount of data written at checkpoint time?" Since I've found it educational to sort through that, I just didn't want the patch modified so that was harder to do than it had to be.
If I thought it worth the trouble to expose that level of information via the stats interface, I'd have submitted that instead of this log-based patch. This circles back to the previous discussion of whether this particular information is strictly developer-level.
