Did not know about Groundhog, thanks. Looking into the docs Groundhog does not support joins (same deal with Persistent), which I'd say is a deal breaker for most (non-trivial) applications.

Acid-state is a different beast entirely, seems to be similar to Clojure's Datomic.

That leaves us with Esqueleto for real world type safe database access (with no SQL Server or Oracle support).

I want to jump ship from Scala to Haskell but there are some gaps to be filled yet before leaving the batteries included Java ecosystem.

Does esqueleto not do it for you? Can you be explitit about whats missing for you? Is it just oracle or sql server support?
