No we do not ship WAL logs. We ship our own transaction logs. One of the
reasons we do this is so you can bring up new slaves live. We do not
support replication of the SQL DDL but you do not need to stop the
replication or stop the database to add tables to the replicated list.

Only that new clusgres thing from LinuxLabs but I would have to see it
in production before I would get anywhere near it.
