Full disclosure - I currently work for Exasol.. but I thought I'd just clarify that Exasol has been around for over 15 years and is far from 'beta' (currently on version 6 with hundreds of production installations worldwide). I've also been in the industry for > 40 years and worked with many database products (including Ingres and Postgres) - and all I can say is download the free community edition from the Exasol website or the Docker image as described above and try it for yourself - you will be up and running very quickly and I think you will be pleasantly surprised regarding both functionality and performance.
