equivalent to "replication_timeout" on standby server

Hi all,

The postgres manual explains the "replication_timeout" to be used to

"Terminate replication connections that are inactive longer than the
specified number of milliseconds. This is useful for the primary server to
detect a standby crash or network outage"

Is there a similar configuration parameter that helps the WAL receiver
processes to terminate the idle connections on the standby servers?

It would be very useful (for monitoring purpose) if the termination of such
an idle connection on either master or standby servers is logged with
appropriate message.

Could some one explain me if this is possible with postgres-9.1.1?

Thanks and Regards,
Samba
