Review comment:
Actually, I'm not quite sure about the question. The `SHOW VIEWS` will
resolve to V1 SessionCatalog which supports `listViews` I think. Do you mean a
custom catalog implements `TableCatalog`(does not support view related
commands) will got error? I'll keep learning the `CatalogPlugIn` related code,
any suggestions would be helpful to me, thanks!
