libpq, binary cursors, & arrays

Hi all,

I'm putting together a small package of macros and functions
to help deal with binary cursor results from libpq, but I've run into a
bit of a stumbling block with regard to array results,

for example:

ArrayType *arr;
uint64_t *lin;

...
res = PQexecParams(conn, "select '{1,2,3}'::bigint[]", 1, NULL,
paramValues, NULL, NULL, 1);
...

arr = (ArrayType *)PQgetvalue(res, 0, 1);
lin = (uint64_t *)ARR_DATA_PTR(lin);
printf("%lld\n", lin[0]);

does not produce the expected results

Any pointers would be much appreciated,

Thanks in advance,
