Given the rather small number of existing uses of CancelRequested, I wonder if it wouldn't be a better idea to rename it to cancel_pressed? Also, perhaps I am missing something, but I do not see anyplace in the current code base that ever *clears* CancelRequested. How much has this code been tested? Is it really sane to remove the setting of that flag from psql_cancel_callback, as this patch does? Is it sane that CancelRequested isn't declared volatile? regards, tom lane
