Review Comment:
Just checked for my own education, what is the content of `ViewVersion`. I
see that there is a `defaultCatalog` member. I don't know much about this code
so asking for my benefit: is this default catalog persisted into view metadata?
When registering the view in catalog1 into catalog2, would the default catalog
be updated too?
