SPI_FINISH(3) PostgreSQL 15.4 Documentation SPI_FINISH(3)
NAME SPI_finish - disconnect a C function from the SPI manager
SYNOPSIS int SPI_finish(void)
DESCRIPTION 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.
RETURN VALUE SPI_OK_FINISH if properly disconnected
SPI_ERROR_UNCONNECTED if called from an unconnected C function
