<code class="function">SPI_execp</code> assumes that no parameters
are null. Otherwise, each entry of the <em class="parameter"><code>nulls</code></em>

value is non-null, or <code class="literal">'n'</code> if the corresponding parameter
value is null. (In the latter case, the actual value in the
corresponding <em class="parameter"><code>values</code></em> entry doesn't matter.) Note
that <em class="parameter"><code>nulls</code></em> is not a text string, just an array:
it does not need a <code class="literal">'\0'</code> terminator.
