Обсуждение: Knowing postgres processes..
Hi,
this are processes running on my box. is it normal to see "idle" processes? 10.10.10.1 holds all of my
applicationthe connects
to the db.. and is it possible to see what query is being processed by the [local] UPDATE?

That says you've got client processes holding open connections without
doing anything. You probably want to look at your client-side logic.

Idle processes are not uncommon on a database. Basically their client applications that don't have anything for the
databaseto do at the present time. Now if they persist for a long period of time without ever changing state to
active,then something is probably wrong.
