postgres killing queries

once in a while our database server get's terrible overloaded, cause people are running thousands of long running queries against it.

1. How to find out who is generating queries:

select datname, client_addr from pg_stat_activity;


2. Killing queries from a specific IP:

select pg_terminate_backend(procpid) from pg_stat_activity where client_addr='IP';

This can be done as postgres user.
