<code class="function">SPI_execute_plan_with_paramlist</code> executes a statement
prepared by <code class="function">SPI_prepare</code>.
This function is equivalent to <code class="function">SPI_execute_plan</code>
except that information about the parameter values to be passed to the
query is presented differently. The <code class="literal">ParamListInfo</code>
representation can be convenient for passing down values that are
already available in that format. It also supports use of dynamic
parameter sets via hook functions specified in <code class="literal">ParamListInfo</code>.
