原因是/etc/init.d/postgresql启动脚本带日志输出参数，去掉即可。（若有需要再开启）

我是先把postgresql一切都先删除，然后下载postgresql的 .run文件安装，跟在win7下安装是一模一样的，安装时路径是按照默认的
主要需要修改的参数如下,参数修改完毕后重启服务,重新连接数据库,对其操作即可查看日志变化情况.

那说明安装文件本身就是有问题的 也有可能是某些部分不支持中文目录 你可以改成英文目录再试试，如果 仍有这样的问题，那说明安装包 制作的时候就有问题了
1、通过命令行查询
\d 数据库 —— 得到所有表的名字
\d 表名 —— 得到表结构
2、通过SQL语句查询
"select * from pg_tables" —— 得到当前db中所有表的信息（这里pg_tables是系统视图）
"select tablename from pg_tables where schemaname='public'" —— 得到所有用户自定义表的名字（这里"tablename"字段是表的名字，"schemaname"是schema的名字。用户自定义的表，如果未经特殊处理，默认都是放在名为public的schema下）
