对于安装
postgresql 9.2我遵循这个url：
http://www.ubuntugeek.com/how-to-install-postgresql-9-2-on-ubuntu-server-using-ppa.html
但是在安装结束时输出如下：
Setting up postgresql-common (140~precise) ... locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_ALL to default locale: No such file or directory Adding user postgres to group ssl-cert Building Postgresql dictionaries from installed myspell/hunspell packages... * No Postgresql clusters exist; see "man pg_createcluster" Setting up postgresql-9.2 (9.2.4-0ppa1~precise) ...

如何解决这个问题？
您的系统区域设置被搞砸了.您的LC_MESSAGES设置为en_IN.UTF-8,但LANG设置为en_US.UTF-8,这是奇怪和不一致的.您是否在〜/ .bash_profile / etc / environment或某事中设置了LC_MESSAGES？
你真的应该dpkg-reconfigure语言环境.见how to select and generate locales in Ubuntu.
一旦你修改了你的区域设置,你可以使用pg_wrapper命令pg_createcluster 9.2 main –start来建立这个错误来建立这个集群.之后,启动服务将会起作用.
