    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      postgresql-9.1                  9.1.5-0ubuntu12.04
    
    Ubuntu 11.10:
      postgresql-9.1                  9.1.5-0ubuntu11.10
    
    Ubuntu 11.04:
      postgresql-8.4                  8.4.13-0ubuntu11.04
    
    Ubuntu 10.04 LTS:
      postgresql-8.4                  8.4.13-0ubuntu10.04
    
    Ubuntu 8.04 LTS:
      postgresql-8.3                  8.3.20-0ubuntu8.04
    
    This update uses a new upstream release, which includes additional bug
    fixes. Due to upstream security policies, this update removes the ability
    of xslt_process() to fetch documents or stylesheets from external URLs.
    Please see http://www.postgresql.org/about/news/1407/ for more information.
    In general, a standard system update will make all the necessary changes.
