Actually, now that I look into it, if we wanted to send SIGUSR1 with a reason to a backend from within postmaster (where processCancelRequest() lives), we'd need to have shared memory access in postmaster which we have not. So the easiest way would be to keep SIGINTs behavior (cancel running statements, not idle transactions) and allow cancellation of idle transactions only via SQL but not via command line. Other ideas?
