New post on ECS vs Objects https://open.substack.com/pub/frest/p/ecs-is-columnar-objects-are-rows?r=qz3e6&utm_medium=ios

In Postgres, we can decide which tables are columnar and which row-based.

I didn’t know psql did columnar, or do you need an extension?

You do need an extension, but it’s readily available and works well. Citus has it built-in, I think.
