      Description

      SQL supports two levels of namespaces, called in the spec catalogs and schemas (with schema being equivalent to Hive's database).  I propose to add the upper level of catalog.  The attached design doc covers the use cases, requirements, and brief discussion of how it will be implemented in a backwards compatible way.
