That would seem logical to me as pgBouncer is just passing the 
connections to the Postgres server, the server is doing the heavy 
lifting of dealing with statements in the connections.

 From the top output it looks like you are working with some form of a 
EDB product. You need to specify what that product is and it's version. 
This list is for the community version of Postgres and people will 
assume that is what you are talking about. There are folks that maybe 
able to help with EDB versions, but they need to know what it is.
