The superuser-only restriction for pg_cancel_backend() has been a pet peeve of mine as well. I actually posted a patch a while back to let users pg_cancel_backend() their own queries, see: http://archives.postgresql.org/pgsql-admin/2010-02/msg00052.php IMO it'd be better to do away with this patch's check of: /* If the user not is the superuser, need to be the db owner. */ and instead just check if the target session's user matches that of the cancel requester. Additionally, this patch keeps all the permission checking inside pg_signal_backend(). That's fine if we're sure that we want pg_cancel_backend() and pg_terminate_backend() to undergo the same permissions check, but perhaps it's a bad idea to relax the permissions check on pg_terminate_backend() ?
