I feel so seen lol. I work in data engineering and the first paragraph is me all the time. There are a lot of cool technologies (timeseries databases, vector databases, stuff like Synapse on Azure, "lakehouses" etc.) but they are mostly for edge cases.

I'm not saying they're useless, but if I see something like that lying around, it's more likely that someone put it there based on vibes rather than an actual engineering need. Postgres is good enough for OpenAI, chances are it's good enough for you.
