First, please excuse me that I'm not able to understand this particular
point clearly. How can be reducing/using fewer connections in connection
pooler can support larger concurrent incoming connection requests?  If this
is so critical to revisit (reducing), then I may have to convince/justify my
peers also, before making this change in the Production server.  Can you
throw some light on this subject?

Thanks for bringing this idea to notice.
