It is approximately equivalent to running the SQL command \fBROLLBACK\fR\&. 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\&. .PP \fBSPI_rollback_and_chain\fR is the same, but the new transaction is started with the same transaction characteristics as the just finished one, like with the SQL command \fBROLLBACK AND CHAIN\fR\&. .PP These functions can only be executed if the SPI connection has been set as nonatomic in the call to \fBSPI_connect_ext\fR\&.
