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.

DBeaver β open-source Database client
DBeaver works surprisingly nicely with less popular DBs. I work with Babelfish for PostgreSQL [1], it supports connections with SQL Server client libs. Most GUI client tools (like SSMS) expect "real" SQL Server on the other end of the wire - depend on various system views for DB introspection, so only partially work with Babelfish. Even if client tool is based on JDBC (like SQuirell SQL), it doesn't guarantee that this tool won't use additional SQL Server-specific querues for i trospection. DBeaver is much better at this, I guess it is using JDBC API or DB-neutral INFORMATION_SCHEMA views.

'We had to educate Oracle about our contract,' CIO says after Big Red audit
Was just about to write that AWS does that, but no, it's only for MS SQL Server: https://babelfishpg.org/, https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide....

The problem with SQL servers licensing costs
Migration to Postgres from MS SQL Server doesn't have to be a complete app rewrite. Obviously any .Net components would be a problem, but if it's just a matter of existing clients and T-SQL, there's always Babelfish.

A Technical Dive into PostgreSQL's replication mechanisms
> moving some data from SQL Server to Postgres
I don't have any first-hand experience with Postgres replication to share, just, when moving DB from MSSQL, Babelfish extensions for Postgres (https://babelfishpg.org/) may be of interest.

The Future of MySQL is PostgreSQL: an extension for the MySQL wire protocol
This is probably referring to "zero changes to your driver code" and not "zero changes to the SQL you send over this driver".
Translating between SQL dialects is notoriously hard and attempts to translate [1] are working in 95% of cases. But the last 5% would require 5x amount of work. That's because "SQL dialect" also includes weird edge cases of type inference of things like COALESCE(5, FALSE) and emulation of system catalogs (pg_catalog, information_schema).

Build the dependency graph of your BigQuery pipelines at no cost: a Python implementation
In the project we used Python lib networkx and a DiGraph object (Direct Graph). To detect a table reference in a Query, we use sqlglot, a SQL parser (among other things) that works well with Bigquery.

sqlglot - Amazing SQL parsing library
Wanted to give sqlglot a shoutout as it saved me a ton of time.
What are some alternatives?
realtime - Broadcast, Presence, and Postgres Changes via WebSockets
sqloxide - Python bindings for sqlparser-rs
JSqlParser - JSqlParser parses an SQL statement and translate it into a hierarchy of Java classes. The generated hierarchy can be navigated using the Visitor Pattern
Transcrypt - Python 3.9 to JavaScript compiler - Lean, fast, open! -
zetasql - ZetaSQL - Analyzer Framework for SQL
duckdb - DuckDB is an in-process SQL OLAP Database Management System
criterion.rs - Statistics-driven benchmarking library for Rust
py2many - Transpiler of Python to many other languages
sirix - SirixDB is an an embeddable, bitemporal, append-only database system and event store, storing immutable lightweight snapshots. It keeps the full history of each resource. Every commit stores a space-efficient snapshot through structural sharing. It is log-structured and never overwrites data. SirixDB uses a novel page-level versioning approach.
splink - Fast, accurate and scalable probabilistic data linkage with support for multiple SQL backends
dbt-unit-testing - This dbt package contains macros to support unit testing that can be (re)used across dbt projects.
