Thanks for your clues.
The system I have used to debug the code is x86 64bit based, Ubuntu 1404
and postgres 9.3.13, I have revised the code and it looks like as following:
Datum vquery(PG_FUNCTION_ARGS) {
int array_len = PG_GETARG_INT32(0);
int64 * node_ids;
ArrayType * retarr;
Datum * vals ;

I have written an extension to manage openstreetmap data. There is a C
function to perform spatial top k query on several tables and return an
array of int8 type as result. The code skeleton of this function is as
follows:
Datum vquery(PG_FUNCTION_ARGS) {
int array_len = PG_GETARG_INT32(0);
long
