<code class="function">SPI_commit</code> commits the current transaction. It is
approximately equivalent to running the SQL
command <code class="command">COMMIT</code>. After the transaction is committed, a
new transaction is automatically started using default transaction
characteristics, so that the caller can continue using SPI facilities.
If there is a failure during commit, the current transaction is instead
rolled back and a new transaction is started, after which the error is
thrown in the usual way.
</p><p>
<code class="function">SPI_commit_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">COMMIT 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>.
