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.

Mangle, a programming language for deductive database programming
There are even table-valued functions.
These things are not widespread, and differ by implementation, and the way these are used by clients are copy-and-paste. Something as thoughtful as ZetaSQL https://github.com/google/zetasql does not have mechanisms for structuring (modules, packages, interfaces). SQL will not, cannot evolve into such a direction (or, anything that evolves, will not be recognizable as SQL).

goccy/bigquery-emulator: BigQuery emulator server implemented in Go
Hi, I develop a BigQuery emulator ( https://github.com/goccy/bigquery-emulator ) from early 2022. It is written in Go, but can be used from bq command line tool and other language's (e.g. Python ) client SDK after installing docker image or released binary. It currently supports over 200 of the nearly 330 standard functions in BigQuery and all data types except GEOGRAPHY ( see https://github.com/goccy/go-zetasqlite#status for details ). ZetaSQL ( https://github.com/google/zetasql ) is used to parse and analyze queries.

Parsing SQL
If you don't want to do it yourself, there's this:
https://github.com/google/zetasql
Parsing is huge but it's amazing how small a part of the job it is. This library isn't even the half of it.

New PostgreSQL Interface for Cloud Spanner
I mean the postgres parser (and semantic changes) for ZetaSQL. The zetasql parser is in a file called zetasql/parser/bison_parser.y, I strongly suspect they now have a file called something like zetasql/pgparser/bison_parser.y as well (and much more pervasive changes to support the deeper differences in the dialects).
This is the lexical structure and syntax docs for the new postgres inteface to cloud spanner:
https://cloud.google.com/spanner/docs/postgresql/lexical
And this is the zetasql lexical structure and syntax docs:
https://github.com/google/zetasql/blob/master/docs/lexical.m...
Notice that the new PG docs are an edit of the Zeta ones - evidence that my hypothesis is correct.
