22.97. Release 0.100

System Connector

The System Connector now works like other connectors: global system tables are only available in the system catalog, rather than in a special schema that is available in every catalog. Additionally, connectors may now provide system tables that are available within that connector’s catalog by implementing the getSystemTables() method on the Connector interface.
