星期五我使用pg_upgradecluster
(在 Debian Buster 上)从 PostgreSQL 13 升级到 14。这很有效,所以今天我想升级另一台服务器(Linux Mint 20.3 Cinnamon)。这一次它不起作用。这是我所做的:
root@farao:~# pg_lsclusters

没有-V
参数,结果是一样的。我做错了什么?我需要安装 PERL 模块吗?
备注我只记得我只安装了 postgresql-13 并使用了仍然存在的数据库和配置。PostgreSQL 是否在某处存储有关它创建的集群的信息initdb
?不合逻辑,因为pg_lsclusters
可以找到它。
