Yeah I've found this quite odd. Even the LLMs want to pressure you to not use Redis and go all in on Postgres. Postgres is great, and I usually use it. But Redis is so trivial to add to your stack and it does what it does really well. Why not use the right tool for the job?

Presumably this is because LLMs just echo all the pro-Postgres Medium articles they've been trained on. They don't have any actual experience.

LLMs from hyperscalers allow for paid advertising

because if you already have postgres, and dont need thousands of k/v per second, then postgres can do the same ?
