Terminate all queries If you want to terminate all running queries, the following statement can be executed: SELECT pg_cancel_backend(pid) FROM pg_stat_activity WHERE state = 'active' and pid <> pg_backend_pid(); The above statement will kill all active queries and should only be used in special situations.
Go to Dashboard in your pgAdmin. At the bottom, in the Server Activity section, under the Sessions Tab, you can see all the Active queries. Now, notice the cross button and the Stop button to the left of each query.
You can use pg_terminate_backend() to kill a connection. You have to be superuser to use this function.
Kill an Idle Connection: We have to provide the process 'id' within the query in a terminate function. >> SELECT pg_terminate_backend(7408); The process has been magnificently killed.
What I did is first check what are the running processes by
SELECT * FROM pg_stat_activity WHERE state = 'active';
Find the process you want to kill, then type:
SELECT pg_cancel_backend(<pid of the process>)
This basically "starts" a request to terminate gracefully, which may be satisfied after some time, though the query comes back immediately.
If the process cannot be killed, try:
SELECT pg_terminate_backend(<pid of the process>)
