在升级9.5到9.6期间无法创建目标群集

Question

我在ubuntu 16.04上，并在其上安装postgres 9.5

然后我将postgres 9.5升级到9.6，然后按postgresql offical download page安装9.6：

然后我运行df1 <- structure(list(col1 = c("{abcd} {efgh} {higk}", "[lmnop] [qrst] [uvwx]" )), .Names = "col1", class = "data.frame", row.names = c(NA, -2L)) ，安装后，我运行以下命令进行升级

apt install postgresql-9.6

然后我尝试使用# stop the 9.6 $ sudo pg_dropcluster 9.6 main --stop # upgrade 9.5 to latest version $ sudo pg_upgradecluster 9.5 main sudo pg_upgradecluster 9.5 main Stopping old cluster... Notice: extra pg_ctl/postgres options given, bypassing systemctl for stop operation Disabling connections to the old cluster during upgrade... Restarting old cluster with restricted connections... Redirecting start request to systemctl perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = "en_US:en", LC_ALL = (unset), LC_CTYPE = "UTF-8", LANG = "en_US.UTF-8" are supported and installed on your system. perl: warning: Falling back to a fallback locale ("en_US.UTF-8"). Error: The locale requested by the environment is invalid. Error: Could not create target cluster 命令连接旧群集。但错误：

psql

似乎pg_hba.conf错了，然后我在$ psql -U postgres -h localhost psql: FATAL: no pg_hba.conf entry for host "::1", user "postgres", database "postgres", SSL on FATAL: no pg_hba.conf entry for host "::1", user "postgres", database "postgres", SSL off 检查了pg_hba.conf，但看起来很好：

/etc/postgresql/9.5/main/pg_hba.conf

Answer 1

我能找到解决此问题的唯一解决方案是运行以​​下命令：

export LC_CTYPE=en_US.UTF-8 export LC_ALL=en_US.UTF-8

继续sudo pg_upgradecluster 9.5 main

解决方案很简单，只需在终端中运行以下命令：

$ sudo locale-gen "en_US:en"
$ sudo locale-gen "en_US.UTF-8"
