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?
