Re: Is there a way to kill a connection from the pg_stat_activitly list?

[Jessica Richard <rjessil@xxxxxxxxx>]

If the connection is from the local machine, I can find it with "ps -ef | grep procpid", then kill it with Unix command "kill" outside Postgres...

But I have many remote connections coming from different machines...it is hard to kill on the OS level outside Postgres on the postgres host...

I am looking for something to kill a Postgres user connection within Postgres...
Some thing like, you find the user connection with select * from pg_stat_activity...then you pick a procpid and kill right there...

Thanks,

Where does pg_ctl kill fit in?

Is TERM the normal signal to use there, too?

Should the pg_ctl docs give some guidelines on the signals?
