+   <code class="function">SPI_copytuple</code> makes a copy of a row in the
+   upper executor context.  This is normally used to return a modified
+   row from a trigger.  In a function declared to return a composite
+   type, use <code class="function">SPI_returntuple</code> instead.

+   This function can only be used while connected to SPI.

+   <code class="symbol">SPI_ERROR_UNCONNECTED</code>.
