I have no reason to believe that and you certainly haven't shown that.

All this shows is the Connection being opened, not closed.
I've implemented an idea I got from rupa in #postgresql a while ago
about a way of logging leaked connections. I've added some code to the
Connection's finalize() method that prints some logging information if
the Connection was not closed. This is enabled by using the new
logUnclosedConnections URL parameter.
See the attached code for an example. I've put up a new jar that
contains this here: http://www.ejurka.com/pgsql/jars/km
import java.sql.*;
public class OpenConn {
public static void main(String args[]) throws Exception {
Class.forName("org.postgresql.Driver");
leakConnection();
System.gc();
}
private static void leakConnection() throws Exception {
Connection conn =
DriverManager.getConnection("jdbc:postgresql://localhost:5810/jurka?logUnclosedConnections=true","jurka","");
}
}
