So, right now the upgrade directory will be something like: ./pg_upgrade_output.d/20250602T095620.137 cleanup_output_dirs() recursively deletes everything in the timestamp directory (and the directory itself), and then it cleans up pg_upgrade_output.d if it is empty. My first thought would be to teach cleanup_output_dirs() to delete everything except for files with the ".txt" suffix (so that future warning files are handled, too). This is a little weird because users will be forced to delete the leftover directories and warning files manually, but I'm not sure it's worth adding different --retain modes for that (e.g., --retain=all, --retain=warnings, --retain=none). -- nathan
