if a new secure execution mechanism is developed in Python. The
writer of a function in untrusted PL/Python must take care that the
function cannot be used to do anything unwanted, since it will be
able to do anything that could be done by a user logged in as the
database administrator. Only superusers can create functions in
untrusted languages such as <literal>plpythonu</literal>.
