> If you need ClientCursor often, you can set the Connection.cursor_factory to have them created by default by Connection.cursor(). This way, Psycopg 3 will behave largely the same way of Psycopg 2. These kind of changes are nice from a migration point of view, but eventually cause a significant amount of inconspicuous bugs. The framework now behaves differently in different applications. And I actually don't like reading about potential client-side merging. I've been taught to only use parameterized queries, and not to write merging myself. I only trust the database to make the right call here.
