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.

Datomic can use various storage services. Yes, pg is one option, but you can have DynamoDB, Cassandra, SQLServer and probably more.

What do you mean? It's append only but you can have CRUD operations on it. You get a view and of the db at any point in time if you so wish, but can support any CRUD use case. What is your concern there?

It will work well if you're read-heavy and the write throughput is not insanely high.

I wouldn't say it's internally more complex than your pg with whatever code you need to make it work for these scenarios like soft-delete.

From the DX perspective is incredibly simple to work on (see Simple Made Easy from Rich Hickey).
