Tom,
we've just had a significant PGX customer encounter this with the latest
Postgres on Redhat's freshly released flagship product. Presumably the
default wal_sync_method will only change prospectively. But this will
feel to every user out there who encounters it like a bug in our code,
and it needs attention. It was darn difficult to diagnose, and many
people will just give up in disgust if they encounter it.
