postgres では、正しいパスワードでロール「dguedes」を作成し、すべての権限を付与しました。例えば：
bash-4.3$ psql -d forum_development -U dguedes
could not change directory to "/home/dguedes/Desktop/forum/clean_forum": Permission denied
Password for user dguedes:
psql (9.3.5)
Type "help" for help.
forum_development=# \du
List of roles
Role name | Attributes | Member of
-----------+------------------------------------------------+-----------
dguedes | Superuser, Create role, Create DB, Replication | {}
postgres | Superuser, Create role, Create DB, Replication | {}
forum_development=#
これは、私の役割が既にすべての権限を持っていることを示しています。
私の ph_hba.conf ファイル:
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
host all all 127.0.0.1/32 ident
# IPv6 local connections:
host all all ::1/128 ident
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres md5
#host replication postgres 127.0.0.1/32 ident
#host replication postgres ::1/128 ident
コマンド「systemctl stop postgresql-9.3」および「systemctl start postgresql-9.3」でサーバーを再起動しましたが、何も起こりませんでした。
最後に、'database.yml' ファイル:
development:
adapter: postgresql
encoding: UTF8
database: forum_development
pool: 5
username: dguedes
password: randompass
host: localhost
test:
adapter: postgresql
encoding: unicode
database: forum_test
pool: 5
username: dguedes
password: randompass
host: localhost
だから、私は問題を理解することはできません。私はすでにpostgreを再インストールしてすべてをきれいにしようとしましたが、うまくいきませんでした。何が間違っているように見えますか?
