Couple of other points here:
*) stats collector process is very long lived and does things, so will
accumulate cpu time according to top over the shorter lived backend
connections
*) most servers are multi core these days...stats will eat at most one core
maybe this is a non-problem? are you seeing other issues outside of
high cpu time according to top?
