Fast Loading

In PostgreSQL each schema type is stored in its own files with its own index,  and every record is accessed separately.  In ZODB,  a single pickle can include many differetnt classes.  Pickles load fast, as a single object access.   In contrast. accessing objects with multiple schemas in Postgress requires accessing multiple files. That is slower.  In practice, to minimize load times,  PostgreSQL developers self-limit the complexity of schemas, making applications  more brittle.
