Best way to construct PostgreSQL ArrayType (_int4) from C int array

[Adrian Schreyer <ams214@xxxxxxxxx>]

At the moment I am using the following code to construct a PostgreSQL
array from a C array in my C extension but I am not so sure if this is
really the best solution:

const int *data = array.data(); // C array
Datum *d = (Datum *) palloc(sizeof(Datum) * size);

for (int i = 0; i < size; i++) d[i] = Int32GetDatum(data[i]);

ArrayType *a = construct_array(d, size, INT4OID, sizeof(int4), true, 'i');

Is this okay or is there a better solution (existing function in the
PostgreSQL source for example)?

Cheers,

Adrian
