SPI_rollback - abort the current transaction
SPI_rollback rolls back the current transaction. It is approximately equivalent to running the SQL command ROLLBACK. After a transaction is rolled back, a new transaction has to be started using SPI_start_transaction before further database actions can be executed. This function can only be executed if the SPI connection has been set as nonatomic in the call to SPI_connect_ext.
