Comment 3 for bug 371806

Okay. I see now that this is also the case with other drivers (e.g. postgres). There are some other issues the patch reflects though which I think are still valid:

1. It should be possible to bypass setting isolation level (by setting isolation=none, for example)
2. The error message related to invalid isolation level (likely copied from postgres driver) incorrectly indicates "autocommit" as a possible option.

Please see my latest patch which sets isolation default back to serializable but also addresses (per revision 278) the above two issues:
