Unload Operation
The unload database operation allows you to completely unload a database and reload it. You can unload an entire database or merely the objects owned by a particular user.
The unload database operation destroys the extended system catalogs and recreates them before loading the data. This is done to guarantee that the data is loaded into system catalogs identical to the ones from which they were unloaded.
