<code class="function">SPI_finish</code> closes an existing connection to
the SPI manager. You must call this function after completing the
SPI operations needed during your C function's current invocation.
You do not need to worry about making this happen, however, if you
abort the transaction via <code class="literal">elog(ERROR)</code>. In that
case SPI will clean itself up automatically.
