Unfortunately I don't have access to a blank database and I took the
chance and ran your tests on a non-empty database. Tests are mostly
good: 5/7 pass. You should know that I used current trunk and simply
commented out the line, which resets the supports_unicode_binds but it
should be equivalent in effect to your patch. Without the patch all
tests fail. Below is pretty verbose result for you.
I hope this helps,
Victor
