Postgresql 当razor用户可以登录到数据库时，razor admin迁移数据库在识别错误时失败

我最近尝试使用此处提供的文档设置Razor服务器：

我首先在Vagrant上重新安装了CentOS 6，然后安装了PostgreSQL server和客户端。然后我从文档中安装了puppet labs RPM。我使用以下方法创建了用户：

su - postgres
createuser -P razor
createdb -O razor razor_prd

然后，我编辑了

/etc/razor/config.yml

文件，以在数据库中反映razor用户的razor密码。然后，当我以root、postgres和razor的身份执行数据库迁移时，我在问题开头的要点中列出了不同的错误

[vagrant@centos6 ~]$ sudo su - razor -c "razor-admin --environment production migrate-database"

不过，我可以以razor用户的身份登录数据库并四处查看，我已经将razor用户的密码重置为postgres，并且仍然可以以razor用户的身份登录。但是，我一直遇到上面列出的错误。我做错了什么

--编辑2015-08-18-- 我在pg_hba.conf中的其他条目上方添加了这些行

# TYPE  DATABASE        USER            ADDRESS                METHOD
local   all             all                                    trust
host    all             all             127.0.0.1/32           trust

现在，我得到一个SQL错误，它说：

E, [2015-08-19T16:26:10.028000 #2203] ERROR -- razor.sequel: Java::OrgPostgresqlUtil::PSQLException: ERROR: syntax error at or near "DEFERRABLE"

我相信这与Razor中的SQL有关

我要做的就是将数据库更新到最新版本。CentOS default repos中的PostgreSQL版本为8.4，已弃用。然后，我还必须将本地设置和主机设置再次列为白名单，以确保信任。然后重新启动PostgreSQL，迁移就成功了
