No, it isn't. What you get is a series of int16 fields:

pq_sendint(&buf, x.ndigits, sizeof(int16));
pq_sendint(&buf, x.weight, sizeof(int16));
pq_sendint(&buf, x.sign, sizeof(int16));
pq_sendint(&buf, x.dscale, sizeof(int16));
for (i = 0; i < x.ndigits; i++)
pq_sendint(&buf, x.digits[i], sizeof(NumericDigit));

Note that the "digits" are base-10000 digits.
