Hwo to set timeout for PHP persistent connections

Ciao guys,

   I need to set a reasonable low value of timeout for inactive
connections, as they seem to stay up when a PHP script calls a
pg_pconnect on the database server.

   As its main purpose is to serve a Web application, I'd love
connections to get close after 10-15 seconds of inactivity.

   Is there a run-time configuration I can set in Postgres?

Ciao and thanks
-Gabriele
