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
