With the v2 command style, we need to extend the `CatalogPlugin` to support view related interface. Which way do you prefer, add listViews function to `TableCatalog` or add new interface `SupportViews`? 2. The current `CatalogPlugin` also does not support `isTemporaryTable` check, so the v2 `ShowTablesExec` and `ShowViewsExec` can not support the isTemporary output column. Do we need to handle it here? Directly calling `SessionCatalog` API instead of 'CatalogPlugin' seems not elegant here, right? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
