SPI_finish — disconnect a C function from the SPI manager
int SPI_finish(void)
SPI_finish
closes an existing connection to
the SPI manager. You must call this function after completing the
SPI operations needed during your C function's current invocation.
You do not need to worry about making this happen, however, if you
abort the transaction via elog(ERROR)
. In that
case SPI will clean itself up automatically.
SPI_OK_FINISH
if properly disconnected
SPI_ERROR_UNCONNECTED
if called from an unconnected C function
