我正在尝试在 Ubuntu 14.04 上安装 Postgres 9.3，但在启动时遇到令人讨厌的错误。这是我所看到的：
$ sudo service postgresql restart
* Restarting PostgreSQL 9.3 database server
* Error: could not exec /usr/lib/postgresql/9.3/bin/pg_ctl /usr/lib/postgresql/9.3/bin/pg_ctl start -D /var/lib/postgresql/9.3/main -l /var/log/postgresql/postgresql-9.3-main.log -s -o -c config_file="/etc/postgresql/9.3/main/postgresql.conf" : [fail]
所以我用这个输出检查了日志文件：
