我在 Amazon EC2 上使用 Ubuntu 12.04 64 位。尝试将 postgresql 从 9.1 升级到 9.2。

$ uname -a
Linux db2 3.2.0-32-virtual #51-Ubuntu SMP Wed Sep 26 21:53:42 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

$ apt-cache policy postgresql
postgresql:
  Installed: 9.1+136~precise
  Candidate: 9.1+136~precise
  Version table:
 *** 9.1+136~precise 0
    500 http://ppa.launchpad.net/pitti/postgresql/ubuntu/ precise/main amd64                 Packages
    100 /var/lib/dpkg/status
 9.1+129ubuntu1 0

 9.1+129 0
    500 http://us-east-1.ec2.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages

我正在遵循的升级过程是:

$ sudo add-apt-repository ppa:pitti/postgresql
$ sudo apt-get update
$ sudo apt-get install postgres-9.2
$ sudo pg_dropcluster --stop 9.2 main
$ sudo pg_upgradecluster 9.1 main /var/lib/postgresql/9.2

任何帮助,将不胜感激。谢谢你。

您的问题的根本原因hot_standbyon在 中postgresql.conf,因此服务器是只读的。

一般来说,如果您在使用Debian 和 Ubuntu 中通常打包pg_upgradeclusterpg_wrapper工具时遇到问题,您可以进行手动集群升级:

  • 启动旧服务器
  • sudo -i -u postgres
  • for db in $(psql --tuples-only template1 -c "select datname from pg_database where datname not in ('template0','template1','postgres','template_postgis');"); do pg_dump -Fc -f $db.backup $db; done
  • pg_dumpall --globals-only > globals.sql
  • 停止旧服务器
  • initdb如果您已将其删除,则在新服务器上创建一个新集群。pg_wrapper我想你用这个pg_createcluster
  • 启动新服务器;仍然作为postgres用户:
  • psql -f globals.sql
  • for backup in *.backup; do pg_restore --dbname postgres --create $backup; done

或者,使用pg_upgrade工具工具就地转换您的数据库,但这可能会使pg_wrapper.

这些步骤可以通过使用pg_dumpall命令进行整个集群转储来简化,但我不太喜欢它。我认为恢复pg_dumpall转储在错误处理方面还有很多不足之处,很难从转储中提取单个数据库或表,并且不能在单个事务中全部恢复。我非常喜欢pg_dumpall只使用全局变量,如用户/组/角色,以及pg_dump单个数据库的每个数据库自定义格式备份,如上所示。

如果您从 apt 安装,则升级的一般步骤。

就我而言,从 pg11 到 pg12:

sudo apt update
sudo apt install postgresql-12
sudo systemctl stop postgresql@12-main #stop the autocreated/autostarted one
pg_dropcluster 12 main # drop it
sudo -u postgres pg_upgradecluster -v 12 11 main

sudo systemctl start postgresql@12-main
sudo -u postgres psql <yourdb> # up and test it
