db connections in session variables

I was wondering if it were possible to store a database connection in a
session variable.

I have tried these 2 methods:

$conn = pg_pconnect("server", "5432", "db");
session_start();
session_register('conn');

$conn = pg_pconnect("server", "5432", "db");
session_id($conn);
session_start();

both of them register a session with the value of "Resource id #1" but
don't act as a db connection.  I am just trying to clean up some code so I
don't have to do a new database connection on every page that I create.

Then if you are able to do this, where would you close the connection?

I guess in ASP, it is possible to store db connections in a session
variable.  I have never done it there either but someone told me that you
can.
