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.

The LZ4 introduced in PostgreSQL 14 provides faster compression
True.
If you're on your way down this rabbit hole, there's a bunch of old-machine-specific compression algorithms, developed by the emulator community, e.g. LZSA: https://github.com/emmanuel-marty/lzsa

Modern LZ Compression
There's quite a lot of retro modern LZ activity too! LZ turns out to be amazing on old machines, often only several times slower than a block copy. Optimal compressors and control over the algorithm have led to some very tight demos.

https://github.com/emmanuel-marty/lzsa - LZSA - a LZ4-like modern LZ that's more efficient both in speed and compression to LZ4 (at least on the 8 bitters it targets).
