Very similar answer to what @FoxMulder900 did, except I could not get his first select to work. This works, though:

WITH long_running AS (
    SELECT pid, now() - pg_stat_activity.query_start AS duration, query, state
    FROM pg_stat_activity
    WHERE (now() - pg_stat_activity.query_start) > interval '1 minutes'
      and state = 'active'
)
SELECT * from long_running;

If you want to kill the processes from long_running just comment out the last line and insert SELECT pg_cancel_backend(long_running.pid) from long_running ;
