SPI_finish
Description
SPI_finish closes an existing connection to the SPI manager. You must call this function after completing the SPI operations needed during your procedure's current invocation. You do not need to worry about making this happen, however, if you abort the transaction viaelog(ERROR). In that case SPI will clean itself up automatically.
IfSPI_finish is called without having a valid connection, it will returnSPI_ERROR_UNCONNECTED. There is no fundamental problem with this; it means that the SPI manager has nothing to do.
