E.g. a SQL may reference a table as `my_catalog.my_db.my_tbl`. catalog name should be excluded in the `CatalogObjectIdentifier`, which would have `my_db.my_tbl`. There were discussions that some catalog servers (like Polaris) have `listCatalogs` endpoint. -- This is an automated message from the Apache Git Service.
