下面是Ubuntu用户的解决方案

首先，我们必须停止postgresql

sudo /etc/init.d/postgresql stop

创建一个名为/etc/apt/sources.list.d/pgdg的新文件。列出并在行下添加

deb http://apt.postgresql.org/pub/repos/apt/ utopic-pgdg main

遵循以下命令

wget -q -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-9.4
sudo pg_dropcluster --stop 9.4 main 
sudo /etc/init.d/postgresql start

现在我们什么都有了，只需要升级如下

sudo pg_upgradecluster 9.3 main
sudo pg_dropcluster 9.3 main

就是这样。大多数升级后的集群将在端口号5433上运行。用下面的命令检查它

sudo pg_lsclusters

Mac通过homebrew:

编译petere/postgresql，

(例如:Brew install peere /postgresql/postgresql-9.6)

删除旧Postgres:

Brew unlink postgresql

编译链接-f postgresql-9.6

如果发生任何错误，不要忘记阅读并遵循每一步的酿造说明。

我认为这是您将postgres更新到9.6的解决方案的最佳链接

站在其他可怜的动物的肩膀上，踩着淤泥，我能够按照以下步骤重新站起来，并在约塞米蒂升级后运行:

假设您已经使用自制程序安装和升级Postgres，您可以执行以下步骤。

Stop current Postgres server: launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist Initialize a new 9.4 database: initdb /usr/local/var/postgres9.4 -E utf8 Install postgres 9.3 (as it was no longer present on my machine): brew install homebrew/versions/postgresql93 Add directories removed during Yosemite upgrade: mkdir -p /usr/local/var/postgres/{pg_tblspc,pg_twophase,pg_stat_tmp}/touch /usr/local/var/postgres/{pg_tblspc,pg_twophase,pg_stat_tmp}/.keep run pg_upgrade: pg_upgrade -v -d /usr/local/var/postgres -D /usr/local/var/postgres9.4 -b /usr/local/Cellar/postgresql93/9.3.5/bin/ -B /usr/local/Cellar/postgresql/9.4.0/bin/ Move new data into place: cd /usr/local/var mv postgres postgres9.3 mv postgres9.4 postgres Restart Postgres: launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist Check /usr/local/var/postgres/server.log for details and to make sure the new server started properly. Finally, re-install related libraries? pip install --upgrade psycopg2 gem uninstall pg gem install pg

这对我很有用。

言简意赅。老实说，我的目标不是理解PostgreSQL的精髓，我只想把事情做好。
