I’m looking for a rather specific point in the design space for database access libraries in Haskell and I’m having some trouble figuring out whether any existing library covers my use cases.
Specifically, I need to
1. get a Yesod application to access a PostgreSQL database without having to reinvent the universe to get them decently integrated,
2. write queries in an EDSL with a good approach to composability and decent static verification against some declared form of the database objects,
3. be able to perform joins
4. be able to specify the schema name for each database object used in queries
I'm working on a Haskell relational query EDSL similar in spirit to HaskellDB. It certainly satisfies your requirements 2 and 3. I'm not exactly sure what exactly your requirements 1 and 4 mean but feel free to contact me off list and we can discuss it further. Tom
