Name and version of the database you are using:
postgresql 8.0

I have a problem with saving new user to my database. user has property surname of type string. When i issue session.save it generates sql query like this: insert into .... values (..., user_surname ,...). The problem is that user_surnmae is not surrounded by apostrophes and postgresql returns an error.
