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!
