I thought I should break the ice here; we currently have 22 subscribers, with names I recognize from acid-state, mysql-simple, postgresql-simple, hssqlppp, persistent, and even PostgreSQL itself. If I've missed anything relevant here, please speak up. So the goal of this list is to help improve the state of database programming in Haskell; I'm not picky about particular topics as long as they are of reasonable quality and relevant to database programming and Haskell. This could be implementing a database in Haskell itself (like acid-state), to interacting with traditional RDBMSes or newer NoSQL systems. My personal interest at the moment primarily lies at coming up with a good mid-level interface to RDBMSes along the lines of the -simple libraries, but I also have interest in an auto-pipelining client library for PostgreSQL, which involves some very low-level details of the PostgreSQL frontend/backend protocol. I'm also interested in higher-level abstractions for dealing with relational databases in general, but I really don't have well-formed opinions on how this should be done. Also while SQL can be cool, it hides that coolness under a lot of syntactic (and some semantic) ugliness; I often wish for a simpler, saner syntax, replacing NULL with algebraic data types, and a richer attribute types, especially relationally valued attributes. So what you interested in?
