psql: FATAL: the database system is in recovery mode - 问题定位方法与解决
首先介绍一下背景，在测试Deepgreen（Greenplum升级版）数据库时，pgbench并发数设置过多，导致数据库卡死了，在进行连接、重启、关闭时，都报同样的错误：psql: FATAL: the database system is in recovery mode。于是尝试进行如下操作，解决了该问题，总体步骤：
- 1.尝试登陆数据库，报错；
- 2.查看Master上的postgres进程，发现有update等待，说明segment上仍然有操作未完成；
- 3、4、5、6.查看4个segment节点的postgres进程，看到有很多pgbench操作idle in transaction，简单判断这些操作已经不工作了，但是仍在事务中，未做处理（idle）；
- 7.通过strace跟踪一个进程，发现果然没有操作；
- 8.把master和segment上的pgbench操作全部杀死；重启数据库，问题解决。
