It's unlikely, but not impossible, if the idle connections
hog enough system resources to affect the server.
Also a very large value for max_connections might affect
performance of some internal data structures
(see http://wiki.postgresql.org/wiki/Number_Of_Database_Connections).
However, idle connections are not the first place where I would
look for the cause of a performance problem.
Connections "idle in transaction" are more likely to cause trouble.
How big is max_connections?
