NAME

       SPI_rollback, SPI_rollback_and_chain - abort the current transaction

SYNOPSIS

       void SPI_rollback(void)

       void SPI_rollback_and_chain(void)

DESCRIPTION

       SPI_rollback rolls back the current transaction. It is approximately equivalent to running
       the SQL command ROLLBACK. 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.

       SPI_rollback_and_chain is the same, but the new transaction is started with the same
       transaction characteristics as the just finished one, like with the SQL command ROLLBACK
       AND CHAIN.

       These functions can only be executed if the SPI connection has been set as nonatomic in
       the call to SPI_connect_ext.
