Beware that this function can return a <code class="type">Portal</code> object
that does not have cursor-like properties; for example it might not
return tuples. If you simply pass the <code class="type">Portal</code> pointer
to other SPI functions, they can defend themselves against such
cases, but caution is appropriate when directly inspecting
the <code class="type">Portal</code>.
