close inactive client connection

Hello,


 I am developing a system, using the ZeosLib, which maintains a permanent connection to the database.


 When the client loses the connection, the server does
not recognize this and keeps the connection as if it were active. When
the client attempts to reconnect, the server creates a new connection
and the previous remains active.
 This has caused an excessive increase in the number of active connections and hampered the use of the system.


 Have any way or setting to make postgres close idle connections?
