A narrow distinction, but Hydra is Postgres - we only install an extension - while Greenplum and Redshift are forks but remain Postgres-compatible (to varying degrees). I'm not up on when Greenplum last merged updates from Postgres, but I would be concerned that it only runs on Ubuntu 18.04. If you have a look at the Greenplum install in ClickBench[1], you'll see it's not a typical Postgres setup. Hopefully we will be able to beat Greenplum straight-up soon. :) Redshift is multi-node, which puts it in a different category -- with considerably higher costs.
