It's probably worth mentioning that people who want to turn off fsync to gain a performance boost should instead look at a RAID controller with a BBU so they can safely enable write-back caching, getting most of the benefits of fsync=off safely.
Which options specifically should be set if a BBU is in use? Obviously fsync should be on always, but can full_page_writes be disabled? Are there other tweaks that can be done?
It would be great to see some practical hints in the documentation while the fsync part is getting changed.
