Nie można utworzyć testowej bazy danych w szynach 3.2 z postgresami

Question

To jest bardzo dziwne. Im próbuje zrobić prosty rake db:test:clone lub tworzyć i bez względu na to, co robię, z wyczyszczenie gemset wypróbowania wszelkiego rodzaju database.yml configs, im coraz najdziwniejszych błąd:

LINE 1: CREATE DATABASE "tdt_test"0.0 

Czy ktoś kiedykolwiek widział czegoś takiego przed? WTF to "0.0 !?" Im działa Rails 3.2, RSpec i pg gem 0.14.1

Answer 1

To jest specyficzna sytuacja, ale może pomóc innym.
