postgresql - fe_sendauth : no password supplied

Question

数据库.yml:

# SQLite version 3.x
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
development:
  adapter: postgresql
  encoding: utf8
  database: sampleapp_dev  #can be anything unique
  #host: localhost
  #username: 7stud
  #password: 

  #adapter: sqlite3
  #database: db/development.sqlite3
  pool: 5
  timeout: 5000

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  adapter: postgresql
  encoding: utf8
  database: sampleapp_test  #can be anything unique
  #host: localhost
  #username: 7stud
  #password: 
  #adapter: sqlite3
  #database: db/test.sqlite3
  pool: 5
  timeout: 5000

production:
  adapter: postgresql
  database: sampleapp_prod   #can be anything unique
  #host: localhost
  #username: 7stud
  #password: 
  #adapter: sqlite3
  #database: db/production.sqlite3
  pool: 5
  timeout: 5000

pg_hba.conf:

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     trust
# IPv4 local connections:
host    all             all             127.0.0.1/32            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local   replication     postgres                                md5
#host    replication     postgres        127.0.0.1/32            md5
#host    replication     postgres        ::1/128                 md5

我把前三行的METHOD从md5改成了trust，还是报错。

无论我在 database.yml 中尝试什么组合，当我这样做时:

~/rails_projects/sample_app4_0$ bundle exec rake db:create:all

我总是得到错误:

fe_sendauth: no password supplied

我按照本教程进行设置:

Mac OSX 10.6.8
PostgreSQL 9.2.4 installed via enterpriseDB installer
Install dir: /Library/PostgreSQL/9.2

Answer 1

对 pg_hba.conf 或 postgresql.conf 文件进行更改后，需要重新加载集群以获取更改。

从命令行:pg_ctl reload

从数据库中(作为 super 用户):select pg_reload_conf();

从 PGAdmin:右键单击数据库名称，选择“重新加载配置”

注意:重新加载不足以进行启用归档、更改 shared_buffers 等更改——这些需要重启集群。
