[Haskell-cafe] Multiple DB drivers in HDBC

[kpierre]

Hello.

I have a problem with migration to HDBC 1.1. My application had
transparent support for multiple database types, because of HDBC's
Connection object. How can I preserve this feature with minimal code
changes?

I tried to use ConnWrapper, as migration guide suggest, but it seems
there's no way to convert arbitrary IConnection object into
ConnWrapper.

Thanks in advance,
    pierre
