<code class="function">SPI_rollback</code> rolls back the current transaction. It
is approximately equivalent to running the SQL
command <code class="command">ROLLBACK</code>. After the transaction is rolled back,
a new transaction is automatically started using default transaction
characteristics, so that the caller can continue using SPI facilities.
</p><p>
<code class="function">SPI_rollback_and_chain</code> is the same, but the new
transaction is started with the same transaction
characteristics as the just finished one, like with the SQL command
<code class="command">ROLLBACK AND CHAIN</code>.
</p><p>
These functions can only be executed if the SPI connection has been set as
nonatomic in the call to <code class="function">SPI_connect_ext</code>.
