----------------------------------

[~liyubin117]  `default_catalog` is usually registered by the Catalog instance. 
I'm wondering what we need to do if we want to save default_catalog to 
CatalogStore. Especially in SqlGateway, DefaultCatalog is not necessarily 
GenericInMemory.  I think  these temporary catalogs should not support `show 
create catalog` ?

> Flink initially creates a default catalog which is included in the 
> `Map<String, Catalog> catalogs`, but is not stored in the CatalogStore.
> After conducting thorough investigation, I've determined that the necessary 
> modification can be made within the `CatalogManager`.
