With RMT hat on, this appears to be making progress. A few questions /
comments for the group:
1. Nikita: Did you have a chance to review Andres's changes as well?
2. There seems to be some, though limited, progress on design docs.
Andres keeps making a point on adding additional comments to the code to
make it easier to follow. Please do not lose sight of this.
3. Robert raised a point about the use of subtransactions and the
increased risk of wraparound on busy systems using the SQL/JSON
features. Do these patches help reduce this risk? I read some clarity on
the use of subtransactions within the patchset, but want to better
understand if the risks pointed out are a concern.
Thanks everyone for your work on this so far!
Jonathan
