 *     <li>the vendor-specific delegate returned by {@link #buildSQLExceptionConversionDelegate()};
 *         (it is strongly recommended that specific Dialect implementations
 *         override {@link #buildSQLExceptionConversionDelegate()})</li>
 *     <li>a delegate that interprets SQLState codes for either X/Open or SQL-2003 codes,
 *         depending on java.sql.DatabaseMetaData#getSQLStateType</li>
 * </ol>
 * <p/>
 * If this method is overridden, it is strongly recommended that the
 * returned {@link SQLExceptionConverter} interpret SQL errors based on
 * vendor-specific error codes rather than the SQLState since the
 * interpretation is more accurate when using vendor-specific ErrorCodes.

 * @return The Dialect's preferred SQLExceptionConverter, or null to
