Use the source Luke ... array_send, in backend/utils/adt/arrayfuncs.c,
does this:
/* Send the array header information */
pq_sendint(&buf, ndim, 4);
pq_sendint(&buf, v->flags, 4);
pq_sendint(&buf, element_type, sizeof(Oid));
for (i = 0; i < ndim; i++)
{
pq_sendint(&buf, ARR_DIMS(v)[i], 4);
pq_sendint(&buf, ARR_LBOUND(v)[i], 4);
}
I believe flags is always 0 at the moment; it might be a good idea
to punt if you see a nonzero there.
