在 postgre DB 上不断运行作业的麻烦，永远不会完成。
我尝试了以下操作来修复它：
- apt-get update & upgrade（postgresql 已更新到最新版本）
/etc/init.d/postgresql 重启
postgresql.service - PostgreSQL RDBMS Loaded: loaded (/lib/systemd/system/postgresql.service; enabled) Active: active (exited) since Fri 2015-10-16 10:06:04 UTC; 9s ago Process: 6787 ExecStart=/bin/true (code=exited, status=0/SUCCESS) Main PID: 6787 (code=exited, status=0/SUCCESS) CGroup: /system.slice/postgresql.service/etc/init.d/pgagent 重启

在

我无法弄清楚实际问题是什么以及如何实际解决它？
我调查的另一件事是pgagent[6793]: *** Caught unhandled unknown exception; terminating可以通过不正确的连接终止来调用......
