Re: SPI_getvalue gives a core dump

I have already tried it out. I tried the following:- 
char *myval
1) i = DatumGetInt64(SPI_getbinval(SPI_tuptable->vals[0], SPI_tuptable->tupdesc, 1, &isnull));
2) myval=SPI_getvalue(trigdata->tg_trigtuple, tupdesc, 17);
3) myval=SPI_getvalue(trigdata->tg_trigtuple, trigdata->tg_relation->rd_att, 17);
4) myval=strdup(SPI_getvalue(trigdata->tg_trigtuple, trigdata->tg_relation->rd_att, 17));
5) if ((myval=SPI_getvalue(trigdata->tg_trigtuple, trigdata->tg_relation->rd_att, 17))==NULL) then, log and exit.


With warm regards.
