Обсуждение: [GSoC] array processing questions
Hi mentors and hackers,
One question about array processing in postgresql. Assume my input is a Datum (which contains an array). Are there any examples to loop through the array and operates on each element? feel like it is not that straight-ford.
Thanks Charles
