Ok.

How does that follow?

Dumb comment. "Not using Microsoft SQL Server" != "don't work with databases" Sensible people prefer Postgres.

"Like last year, MySQL is the most commonly used database. PostgreSQL has taken the second spot this year."

SO has a somewhat "niche" audience- most of the MS stack has a single source of truth about documentation (and it's detailed). People using MS stack are also the people using MS SQL Server.

Btw, do you know if the MS SQL server perf analysis tools are available for linux?

Microsoft SQL server ain’t free to use in production.
