Would that mean that a controlled restart of the old master so that the
recovery stops before applying the logs that were not shipped to the
slave would put it in the same situation?
How easy is it to script that? It seems all we need is the current XID
of the slave at the end of recovery. It should be in the log, maybe it's
easy enough to expose it at the SQL level…
