Re: [GSoC] Question about returning bytea array

Hi Aleksander,

   I have the requirements to return a bytea array for some functions in pg_thrift plugin. 

What I did was similar to the following,

bytea** ret = palloc(len * sizeof(bytea*));

for (int i = 0; i < len; i++) {

   // allocate space

   ret[i] = palloc(size);

   // fill in ret[i]

   ...

}

PG_RETURN_POINTER(ret);

I can verify each ret[i] is correct by logging, but server crash when 

executed PG_RETURN_POINTER(ret). 

So, I am wondering what's the reason of the crash? 

and what's the recommended way (best practice) to construct a return value to be bytea array?
