Обсуждение: problem with PSQLException/PSQLState

Just discovered a possible issue with the SQLException thrown by the 7.4
beta3 jdbc driver.

PSQLException used to contain only a message, but now also has a ref to
org.postgresql.util.PSQLState.  PSQLState isn't serializable and because
a SQLException is supposed to be serializable, this causes a problem in
situations where you might want to propogate your exceptions across the
wire (i.e. app server to client).

The problem is fixed if you change PSQLState to implement Serializable,
as follows:

[[SNIP

package org.postgresql.util;

import java.io.Serializable;

public class PSQLState implements Serializable
{

]]

Here's a patch to add the change indicated and more importantly a test
case so this won't happen again.
