SPI_freetuptable
frees a row set created by a prior SPI command execution function, such as
SPI_execute
. Therefore, this function is usually called with the global variable
SPI_tupletable
as argument.
This function is useful if a SPI procedure 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
SPI_finish
.
