postgresql backend doesn't cast empty strings to unicode

[John Shaffer <jshaffer2112@…>]

As far as I am aware, every other backend returns every string as unicode.

This is very minor in practice, but it does make doctests uglier.

Exactly which version of psycopg are you seeing this with?

libpq5 8.2.4-0ubuntu0.7.04
python-psycopg 1.1.21-13ubuntu1
python 2.5.1-0ubuntu1

Indeed. Should be easy to fix, too. I'll do it this afternoon.
