无法登录PostgreSQL数据库

create user blog with password 'blog';

然后我把它作为数据库的所有者：

alter database blog_development owner to blog;

然后我试图登录,它没有工作：

$psql -d blog_development -U blog -W
Password for user blog:
psql: FATAL:  Ident authentication failed for user "blog"

任何想法为什么？

我尝试过的一件事是编辑pg_hba.conf

76 # Database administrative login by UNIX sockets
 77 local   all                postgres                          ident
 78
 79 # TYPE  DATABASE           USER        CIDR-ADDRESS          METHOD
 80
 81 # "local" is for Unix domain socket connections only
 82 local   all                all                               ident
 83 # IPv4 local connections:
 84 host    all                all         127.0.0.1/32          md5
 85 host    blog_development   blog        127.0.0.1/32          md5
 86 # IPv6 local connections:
 87 host    all                all         ::1/128               md5

85号线是我补充的.之后我重新启动了PostgreSQL,但似乎没有改变任何东西.
