Blob .getBytes position should start at 1 - Mailing list pgsql-patches

 From the Javadoc of java.sql.Blob byte[] getBytes(long pos, int length)
throws SQLException;

   * @param pos the ordinal position of the first byte in the
   *        <code>BLOB</code> value to be extracted; the first byte is at
   *        position 1

pqsql driver assumes the position starts from 0
