Docbug, SPI_getbinval, triger example

The docs suggest that this:
       /* Get number of tuples in relation */       ret = SPI_exec("select count(*) from ttest", 0);
       if (ret < 0)               elog(NOTICE, "trigf (fired %s): SPI_exec returned %d",
when, ret);
       i = SPI_getbinval(SPI_tuptable->vals[0], SPI_tuptable->tupdesc,
1, &isnull);       elog (NOTICE, "trigf(fired %s): there are %d tuples in ttest",
when, i);


When it should be:
       pi = SPI_getbinval(SPI_tuptable->vals[0], SPI_tuptable->tupdesc,
1, &isnull);       elog (NOTICE, "trigf(fired %s): there are %d tuples in ttest",
when, *pi);
