There was a problem hiding this comment.
Though I'm not confident with the authz semantics against nested namespaces, can this properly handle the case where 403 Forbidden happens?

SHOW SCHEAMS with REST catalog in the Trino Iceberg connector currently gets namespaces recursively
for non-leaf namespaces. It can be time-consuming.
This PR introduces a new recursive option to the REST catalog and the SupportsNamespaces interface
so we can get all namespaces with a single request.
Fixes #13453.
It seems the request comes from the DuckDB community. It's helpful for Trino as well.
