Not everyone can use datomic though, for many reasons (including cost). I'd love to use datomic, but its just not an option for me, while postgres is (and the DigitalOcean hosted postgres is quite affordable too and supports TimescaleDB too).
Would that be the community version of Timescale then?
Looks like this is a whole new extension, does DO allow you to install your own, or do you think it'd be easy to make a case for them adding this one? (I'm not a DO user myself)
This is in the TimescaleDB Toolkit extension [1] which is licensed under our community license for now and it's not available on DO. It is available on our cloud service fully managed. You can also install it and run it for free yourself.
