If you're implementing immutable DB semantics maybe you should consider Datomic or alternatives because then you get that for free, for everything, and you also get time travel which is an amazing feature on top. It lets you be able to see the full, coherent state of the DB at any moment!
My understanding is that Datomic uses something like Postgres as a storage backend. Am I right?
Also, it doesn't support non-immutable use cases AFAIK, so if you need both you have to use two database technologies (interfaces?), which can add complexity.
