Thanks.

But what is the process id that is attached to the connection? Can I track down or debug/ get more information related
tothat process id?

The whole point of a connection pool is to keep open connections to the database.  These connections, when not in use,
are"IDLE".  I would expect to see a single connection for every permanent pool connection. 

I don't see any problem with what you show and describe other than I'd expect more than 2 idle connections and I'd
expectthe supposed "problem" to be persistent. 

In your example the backend has been alive and in the pool since 9/11 and the most recent time it was used was 10/2.
Inbetween those two dates there were many other times the connection was used.
