No, I don't. The only thing I do there is        unsigned char *in = PG_GETARG_CSTRING(0);//"AABBCCDDEE1122";//
and return the pointer to the palloced constructed standard varlena 
datum with

typedef struct
{        int4 length;        unsigned char data[1];
} image;
        image *im = (image *) palloc(VARHDRSZ + out_len);        memset(im, 0, VARHDRSZ + out_len);     im->length =
out_len+ VARHDRSZ;    /* fill the im->data    .......     */        PG_RETURN_POINTER(im);
