Seems it _was_ default in 8.0 and 8.0.1 (called fsync) but
renamed to fsync_writethrough in 8.0.2 and moved away from being
default.

Now, 8.0.2 was released on 2005-04-07 and first destruction
happened in 2005-07-20.  If this says anything about future,
I don't think PostgreSQL will stay known as 'reliable' database.
