(PostgreSQL: Insecure temporary file use in make_oidjoins_check)

    The make_oidjoins_check script insecurely creates temporary files in
    world-writeable directories with predictable names.
  
Impact :

    A local attacker could create symbolic links in the temporary files
    directory, pointing to a valid file somewhere on the filesystem. When
    make_oidjoins_check is called, this would result in file overwrite with
    the rights of the user running the utility, which could be the root
    user.
  
Workaround :

    There is no known workaround at this time."
