PasswordType not supported in Postgres
Actually it was a problem with Alembic migration, in migration table must be also created with the PasswordType, not String or any other type
In SQLAlchemy, when I try to query for user by 
request.db.query(models.User.password).filter(models.User.email == email).first()
Of course it works with different DB (SQLite3).
The source of the problem is, that the password is 
sqlalchemy.Column(sqlalchemy_utils.types.passwordPasswordType(schemes=['pbkdf2_sha512']), nullable=False)
I really don't know how to solve it
I'm using psycopg2
