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.
