Therefore, this function is often called with the global variable \fISPI_tuptable\fR as argument\&. .PP This function is useful if an SPI\-using C function needs to execute multiple commands and does not want to keep the results of earlier commands around until it ends\&. Note that any unfreed row sets will be freed anyway at \fBSPI_finish\fR\&. Also, if a subtransaction is started and then aborted within execution of an SPI\-using C function, SPI automatically frees any row sets created while the subtransaction was running\&. .PP Beginning in PostgreSQL 9\&.3, \fBSPI_freetuptable\fR contains guard logic to protect against duplicate deletion requests for the same row set\&. In previous releases, duplicate deletions would lead to crashes\&. .SH "ARGUMENTS" .PP SPITupleTable * \fItuptable\fR .RS 4 pointer to row set to free, or NULL to do nothing .RE
