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?
