Hi,
 JDBC is causing the connection to close on executing a simple COPY query which the driver does not support. The code shows that driver throws an exception however explicitly the connection is not closed. Consider the following case.
<code>
Class.forName("org.postgresql.Driver");
Connection con = DriverManager.getConnection("jdbc:postgresql://localhost/postgres","altaf","");

Statement stmt = con.createStatement();
stmt.execute("create table abc(a int4)");
try{
        stmt.execute("COPY abc TO STDOUT WITH DELIMITER '|'");
        }catch(Exception e) {
            e.printStackTrace();
        }
        stmt.execute("Select * from abc");

</code>

Can anybody tell what's happening?

At what point can you determine the connection is closed ? Can you do con.createStatement after the exception ?
