You killed the script, but you did not cancel the queries.

Maybe you should change the script so that it cancels the queries when it is killed.

To get rid of the database sessions, do the following as superuser (because you are on 9.1):

SELECT pg_terminate_backend(28223);
SELECT pg_terminate_backend(3722);
