+Resource listings (`list_secrets`, `list_views`, `list_jobs`, `list_functions`, and
+`list_materialized_views`) return lazy iterators. Use `list(db.list_views())` to
+collect synchronous results, or `[name async for name in db.list_views()]` with
+an asynchronous connection. `page_limit` controls each request, and `page_token`
+resumes a listing. Drain the iterator's cached results before saving its token.
