I change :
pm->data[i][j]= DatumGetInt32(SPI_getbinval(tuple,tupdesc, j, &isnull));
To :
pm->data[i][j]= DatumGetInt32(SPI_getbinval(tuple,tupdesc, j+1, &isnull));
In :

In fact "SPI_getbinval(tuple,tupdesc, 0, &isnull));" returns NULL;

HOWEVER THE SECOND PROBLEM IS STILL OPEN !

Thanks for your reading!
