Question

所以我已经看到很多这些问题，但没有一个我需要的答案。大多数都有postgres设置问题或密码错字等。

我遇到了与Rails 3.2无关的Postgres数据库连接问题。

Postgres 9.1对其他rails项目工作得很好。 pg_hba.conf设置为默认值，从不需要更改。
我正在使用与其他项目完全相同的database.yml文件，只是数据库名称不同。我之前从未遇到过这个问题，而且我还有大约20个使用postgres的其他rails项目都工作正常。
我正在与名为postgres

我的database.yml文件：

connection: &connection
  adapter: postgresql
  username: postgres
  password: mypassword
  encoding: unicode
  pool: 5

development:
  <<: *connection
  database: projectname_development

test:
  <<: *connection
  database: projectname_test

production:
  <<: *connection
  database: projectname_production

我得到的错误是：

/home/username/.rvm/rubies/ruby-2.1.1/bin/ruby -S rspec   
./spec/controllers/keyword_lists_controller_spec.rb     
./spec/controllers/map_keywords_controller_spec.rb ./spec/full_stack/document_import_spec.rb

但是，我在这里向PGConnection注入了一些代码：

# Connects to a PostgreSQL server and sets up the adapter depending on the
# connected server's characteristics.
def connect
puts Rails.env
puts @connection_parameters.inspect
@connection = PGconn.connect(*@connection_parameters)
# etc.

输出是（我发现这有点奇怪，但可能是连接对象的一部分？）：

test

test
["", 5432, nil, nil, "postgres", "postgres", "mypassword"]
test

test

NOTICE:  CREATE TABLE will create implicit sequence "bookmarks_id_seq" for serial column "bookmarks.id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "bookmarks_pkey" for table "bookmarks"

#.... a whole bunch more of these....

/home/username/.rvm/rubies/ruby-2.1.1/bin/ruby -S rspec lots_of_spec_files_spec.rb failed

更多：

如果我只是在终端中运行bundle exec rspec spec/它运行正常。但是，如果我运行bundle exec cucumber，则会抛出此错误。我可以用任何其他项目运行黄瓜，这很好。
如果我在终端中运行rake任务，它会运行/home/username/.rvm/rubies/ruby-2.1.1/bin/ruby -S rspec ...many *_spec.rb files，但由于上述错误而失败。

编辑：按照建议增加了一些输出。

任何帮助表示赞赏！

我能够解决此错误的唯一方法是将所有数据库配置从trust放到md5并创建一个新的postgres用户，其名称与我在Ubuntu上的登录名相同

不是一个很好的解决方案，我承认，但它已经成功了。因为我没有将我的数据库用于除了开发之外的任何东西。

Rails：fe_sendauth：没有提供密码（PG ::错误）
