SPI_FINISH(3)            PostgreSQL 16.2 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
