Agreed.  The application should have no knowledge of or concern with the physical connections.

No, an instance of PooledConnection is the so-called physical connection object.  Note that
PooledConnection is not to be used by the application, but rather only by the pool manager
to get connections from the JDBC driver.  No application writer should be looking at the PooledConnection
interface - it is of no interest to the app.
