I'd love to have any kind of progress indication for any sorts that spill to disk, and there's any number of other long-running operations where progress info would be very welcome. I certainly wouldn't let lack of a progress indicator for sorts prevent you from adding one. I like the idea of periodically updating both current_query and the commandline that ps shows. -- Jim C.
