[Haskell-cafe] hdbc, Oracle, and Solaris

Hello folks. I don't understand whether hdbc has a specific Oracle backend or not (not via odbc). It is listed in the description of hdbc, but not really found elsewhere, it seems. I'd like to have a non-odbc support because it is very desirable to have it working on Solaris, and I'm not sure if it will be easy to set it up with odbc there. So, the question might go: has somebody had success with native Oracle support on Solaris with hdbc? Well, or hsql?
