数据库 "postgres" 的 Postgres 从 10.4 升级到 11.5 编码不匹配：旧 "SQL_ASCII"、新 "UTF8"

Question

目前正在检查将 Postgres 从 10.4 升级到 11.5 的过程。

当我运行 pg_upgrade 使用 "check" 选项时，我收到以下消息。如果您对此有任何意见，关于您如何解决这个问题，我将不胜感激。

bash-4.2$ /usr/pgsql-11/bin/pg_upgrade \
> -b /usr/pgsql-10/bin \
> -B /usr/pgsql-11/bin \
> -d /var/lib/pgsql/10/data \
> -D /var/lib/pgsql/11/data \
> -c pgsql-10/ pgsql-11/

encodings for database "postgres" do not match:  old "SQL_ASCII", new "UTF8"
Failure, exiting

Answer 1

当您初始化新服务器时，您需要将其设置为与旧服务器匹配。类似于其中之一：

initdb --locale C  -D /var/lib/pgsql/11/data
pg_ctl initdb -o "--locale C"  -D /var/lib/pgsql/11/data
LC_ALL=C initdb  -D /var/lib/pgsql/11/data

Answer 2

您需要使用与旧集群相同（可恶）的编码来创建新集群：

initdb -E SQL_ASCII --locale=C /new/data/directory

Answer 3

@jjanes, Laurenz Albe 谢谢你的评论，我第一次不明白，根据文件我试图执行以下命令：#/usr/pgsql-11/bin/postgresql-11-setup initdb --locale=C -D /var/lib/pgsql/11/data
但是它在下降，然后我按照你的建议执行了命令并且验证成功：/usr/pgsql-11/bin/initdb --locale=C -D /var/lib/pgsql/11/data

-bash-4.2$ /usr/pgsql-11/bin/pg_upgrade \
> -b /usr/pgsql-10/bin \
> -B /usr/pgsql-11/bin \
> -d /var/lib/pgsql/10/data \
> -D /var/lib/pgsql/11/data \
> -c pgsql-10/ pgsql-11/

现在，我有第二个问题，是否可以从我的源 postgres 数据库更改编码？如果我决定只避免这种情况并继续默认使用 SQL_ASCII，它会以何种方式影响？

数据库 "postgres" 的 Postgres 从 10.4 升级到 11.5 编码不匹配：旧 "SQL_ASCII"、新 "UTF8"
