Well, you really have to sync the data pages BEFORE sync'ing pg_log.
Our buffered logging idea for post-6.3 will do exactly that. I don't
think it is a workaround. You could get pg_log to disk saying a
transaction is complete without getting all the data pages to disk if
the crash happened during the sync.
