Обсуждение: [GSoC] Second period status report for the de-TOAST iterator

It's a report about my GSoC project[1] during the second period.

What I've done:

- Submitted the patch[2] to optimize partial TOAST decompression

- Submitted the patch[3] as a prototype of de-TOAST iterator and tested its performance on position() function

- Perfected patches according to hacker's review comments

What I'm doing:

- Make overall tests on the iterator
- Applying the de-TOAST iterator to the json/jsonb data type

Thanks to hackers and mentors for helping me advance this project.
