Poem

🐰 A new path through Elixir's gleaming code,
With Postgrex as guide along the road,
Grid cards arranged with care and style divine,
Java and Elixir now in perfect line! ✨

I'm wondering why Elixir, do we know users using it?

Neither people nor ether know on a wider scale that CrateDB is PostgreSQL compatible.

There have been interested people from the Erlang community back in a time when the company was still much better having proper conversations with developer communities.
