How does PG determine if a process is <IDLE> ? It there some sort of timeout? I want to be able to distinguish between somene who's interrupted on the phone for a couple minutes vs the guy who left the program running over the weekend. -----Original Message----- From: pgsql-general-owner@xxxxxxxxxxxxxx [mailto:pgsql-general-owner@xxxxxxxxxxxxxx] On Behalf Of Dean Rasheed Sent: Wednesday, August 04, 2010 10:26 AM To: Vick Khera Cc: pgsql-general Subject: Re: killing idle attaches without killing others On 4 August 2010 15:18, Vick Khera <vivek@xxxxxxxxx> wrote: > On Wed, Aug 4, 2010 at 10:03 AM, Gauthier, Dave <dave.gauthier@xxxxxxxxx> > wrote: >> >> How can one kill just the <IDLE> processes I see attached to a DB (from >> pg_stat_activity) without disturbing the others?

That's a SIGINT, but it doesn't actually kill the process, it just cancels it's current query. pg_terminate_backend() sends a SIGTERM to terminate the backend. I think that function is new to 8.4, but you can still manually send the signal if you're on 8.3. http://www.postgresql.org/docs/current/static/functions-admin.html Regards, Dean -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
