Which database and ORM to choose for Scala?

Question

PostgreSQL

Now I'm deciding on a library and database for use in the rock, under the Lift framework.
Mongo likes the flexibility of collections, storing JSON and small files, but as it turned out, under Scala, the most famous libraries do not work with it.
The tasks for the database are simple and there will be no heavy load, the main thing is ease of use, and most importantly, migrations. I will store a lot of serialized JSON data, and do a simple search on it. That's actually all.
Which solution is best for you?
