Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Implementing system-versioned tables in Postgres
I have implemented this for our tool NF Compose that allows us to build REST APIs without writing a single line of code [0]. I didn't go the route of triggers because we generate database tables automatically and we used to have a crazy versioning scheme that was inspired by data vault and anchor modelling where we stored every change on every attribute as a new record.
Sounded cool, but in practice it was really slow. The techniques that are usually employed by Data Vault to fix this issue seemed too complex. Over time we moved to an implementation that handles the historization dynamically at runtime by generating SQL queries ourselves [1]. On a sidenote: Generating SQL in python sounds dangerous, but we spent a lot of time on making it secure. We even have a linter that checks that everything is escaped properly whenever we are in dev mode [2]

- GitHub - neuroforgede/nfcompose: NF Compose is a (data) integration platform that allows developers to define REST APIs in seconds instead of hours. Generated REST APIs are backed by postgres and support automatic consumer notifications on data changes out of the box.

NF Compose – define REST APIs in seconds instead of hours
As part of our services we also provide support for building integrations between (our) systems and external systems. As we didn't want to keep building the same REST APIs every time, we set out to build a standardized data integratin platform that allows for a quick way to generate user specified REST API definitions via a REST API. This has become NF Compose (https://github.com/neuroforgede/nfcompose).

The Guide to PostgreSQL Data Change Tracking
Hey I'm one of the maintainers of https://github.com/BemiHQ/bemi that was recommended in the article. Please feel free to ask me any questions!

Implementing system-versioned tables in Postgres
This is actually what we're @ Bemi https://bemi.io/
We're hoping to make it so that this becomes automatic with Postgres vs moving to specialized databases.
We recently open sourced the core tech that implements system versioned tables https://github.com/BemiHQ/bemi, check it out if interested :)
