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);
