9.6 and fsync=off

After helping clean up the mess from another user who turned fsync=off because they read (bad) tuning advice that it was faster, I'd really like to change the config file comment.

Really.

#fsync = on                             # turns forced synchronization on or off

Now, we can't rename fsync to disable_crash_safety=on or corrupt_my_database=on. But the comment needs changing.

How about:

#fsync = on                             # force disk flushes required for crash safety

or, preferably something like:

"Enable forced disk flushes when they are required for crash safety. Disabling fsync can lead to unrecoverable database corruption in a crash of the host system."
