在RedHat中从postgresql 9.2升级到9.6时unix_socket_directory出错

Question

我已经将我的postgresql服务器9.2升级到9.6了几个小时。这就是我所做的：

把它当作postgres：

/usr/pgsql-9.6/bin/pg_upgrade --old-bindir=/usr/bin/ --new-bindir=/usr/pgsql-9.6/bin/ --old-datadir=/var/lib/pgsql/data/ --new-datadir=/var/lib/pgsql/9.6/data/ --check

得到了输出：

Performing Consistency Checks on Old Live Server

*Clusters are compatible*

好的一切都好，我们走了，让我们尝试升级。

首先，以root身份运行，如here所述：

service postgresql stop

然后，升级命令（作为postgres用户）：

/usr/pgsql-9.6/bin/pg_upgrade --old-bindir=/usr/bin/ --new-bindir=/usr/pgsql-9.6/bin/ --old-datadir=/var/lib/pgsql/data/ --new-datadir=/var/lib/pgsql/9.6/data/

在/var/lib/pgsql/data/pg_upgrade_server.log文件中获得了ERROR输出：

271 -----------------------------------------------------------------
272   pg_upgrade run on Fri Mar  2 15:44:09 2018

276 waiting for server to start....FATAL:  unrecognized configuration parameter "unix_socket_directory"

怎么做到这一点？

任何人？
