Is changing the OS/X wal_sync_method default something we should consider?
It's certainly reasonable to consider changing both OS X and Windows so wal_sync_method defaulted to fsync_writethrough, and provide safer operation by default on both those platforms. It would also result in a mass of complaints that PG 9.0 was much slower than 8.4 from people who were running it in an unsafe way before. Given that we're already starting to see that bad PR on Linux+ext4: http://www.phoronix.com/scan.php?page=article&item=ext4_then_now&num=3
I wonder whether it's the right time for the "reliable is the default on every platform" to just suck up and adopt everywhere, if we're already going to be fighting this "why is PG so slow on recent Linux versions?" PR campaign anyway.
