Không thể tạo cơ sở dữ liệu thử nghiệm trong đường ray 3.2 với postgres

Question

Đây là một điểm cực kỳ kỳ lạ. Im cố gắng để làm một đơn giản rake db:test:clone hoặc tạo và không có vấn đề gì tôi làm, từ thanh toán bù trừ các gemset để thử tất cả các loại database.yml configs, im nhận được lỗi lạ lùng nhất:

LINE 1: CREATE DATABASE "tdt_test"0.0 

Có ai đã từng nhìn thấy bất cứ điều gì như thế này trước? WTF là "0.0 !?" Im chạy Rails 3.2, RSpec và pg gem 0.14.1
