Review comment:
I have a question. We have the following in `ResolveSessionCatalog.scala`:
```scala
case ShowTablesStatement(Some(CatalogAndNamespace(catalog, ns)), pattern)
if isSessionCatalog(catalog) =>
```
Do we plan to add these statements here and not resolve
`UnresolvedNamespace` and let `ResolveSessionCatalog` handle them?
