All the 'dump something' CLI commands now have a new mandatory argument -- name of the file where to dump the data. This allows for more flexible dumping even for production deployments where the debug output is by default off. Also the dump commands are now restricted (they weren't before) to assure that only the appropriate users can run these time consuming commands.
