Let me clarify three things:

1) I started on a MySQL backend a while ago, and didn't do much work on it. 2) Someone else (I won't point fingers, he can stand up himself if he chooses) is working on a MySQL backend.

Standing up :P

I'm going to get on with it this week; hopefully I'll have something to show for it in a few days.

3) Adding arbitrary backends is very easy, *except* for migration support. So it's within the realm of reason to create a HDBC-generic backend, sans migration support.

Indeed, migration is the tedious bit. Migration in Postgre is easier than MySQL.

In fact, the PostgreSQL backend is basically an HDBC backend already; if this is a feature people will actually use, let's do it.

Are you still preferring the native binding route (ala persistent-sqlite)? This is the route I have gone for the MySQL binding.

Yes, that's still the preferred route. I only mention having an HDBC-universal backend because it would be relatively painless to implement. Michael

I vote for ODBC support with GenericSql. ODBC will allow many other databases support.

it doesn't compile. Perhaps a day's work to get it going. Postgresql and sqlite both use a GenericSql module that MySQL can also use. Either way, there are already example SQL backends. You are the first haskeller I have seen show interest in MySQL for a new project, which is the main reasons why that backend is bit-rotting.
