You’re paying EUR3K/month for a cloud warehouse. Your Postgres could’ve handled it.
I see this regularly. A growing company with 15 employees, 200GB of data, and someone convinced them they need a cloud warehouse + dbt + Fivetran + Looker. That’s EUR3K/month before anyone writes a query.
The problem isn’t the tools. The tools are fine. The problem is buying them before you have the problems they solve.
Postgres as your analytical warehouse, dbt on top, and a decent BI tool will carry a 15-person company further than most people think. Not glamorous. Gets the job done. I’ve seen a 500GB partitioned Postgres warehouse serve 50 analysts without breaking a sweat.
So when do you actually need a cloud data warehouse? When Postgres-as-warehouse hits its ceiling:
- Your analytical queries on 100M+ rows are taking minutes instead of seconds (and even then)
- You can’t scale compute independently from storage - one heavy query slows everything down for everyone
- You’re managing partitions, vacuuming, and index tuning instead of building data products
Until then, you’re solving problems you don’t have yet.
I probably could’ve saved three clients six-figure tool investments last year by asking one question earlier: “What’s actually breaking right now?”
If the answer is “nothing, but we want to be ready” - you’re not ready. You’re over-engineering.
And if you’re worried about being stuck later: migrating from Postgres to a cloud warehouse when you actually need it is a well-trodden path. It’s a solved problem.
Can you justify the ROI of every tool in your current data stack?
