> When no default catalog is set, the session catalog (v1) is responsible for table identifiers
with no catalog part. When CTAS creates a table with a v2 provider, a v2 catalog is required
and the default catalog is used. But this may cause Spark to create a table in a catalog
that it cannot use to look up the table.
> In this case, a v2 catalog that delegates to the session catalog should be used instead.
