I don't see any reason/need to replay a log file to a database backend.
One of the benefits of the SQL storage backend is that changes are
committed to storage immediately.  So basically, so long as you don't
have a system-wide crash, there is a very small window where you could
lose data, and at worst you'd only lose a single transaction.

So I don't see why you would want or need to replay logs with SQL.

Is there a specific use-case here that I missed?
