This is ranting.

I am a Postgres proponent but saying that PostgresSQL/mySQL/SQLite is the better choice in the vast majority of cases the parent has come across is reckless. The words were well chosen making the rant not that obvious.

There aren't good or bad DBs. Every DB has its strengths and respective trade-offs. As much I like Postgres, there so many use cases to use also other DBs and also NoSQL ones. I am not feeding the troll and starting reasoning why NoSQL can be terrific or SQL can be a big struggle, I am on both sides, both SQL and NoSQL have their place.

It's sad that a thread which is about learning NoSQL gets hijacked by a unrelated top comment opposing NoSQL.
