Helo guys,
直升机的家伙,

当我试图在页面上导航时，我有一个错误。错误提示:“增加max_prepared_transactions(当前为1)”。

You need a server restart after you change max_prepared_transactions, see the documentation.
在更改max_prepared_transactions后，需要重新启动服务器，请参阅文档。
A reload is not enough.
重新加载是不够的。
You won't be able to do this with pgAdmin III.
你不能用pgAdmin III来做这个。

为了回答你的问题，
-
You need to increase the number of
max_prepared_transactionsfrom 1 to whichever number you feel suits your requirement (but a number lesser than 100 is suggested). The change in configuration will take affect only after a server restart as @Laurenz Albe suggested!您需要将max_prepared_transactions的数量从1增加到您认为符合您要求的任意数量(但建议小于100的数字)。配置的更改将仅在服务器重新启动后才生效，如@Laurenz Albe建议!
-
You'll have to search for a file named
postgresql.confinstead ofpostgresql.config(which is wrong and you'll never find this file on your configured PostgreSQL server), which is generally found under the/datafolder of your PostgreSQL installation (and exactly the folder structure that you've shared in your question's screenshot earlier)!您必须搜索名为postgresql的文件。conf代替postgresql。config(这是错误的，你永远不会在你配置的PostgreSQL服务器上找到这个文件)，它通常是在PostgreSQL安装的/data文件夹下找到的(以及之前在你的问题截图*享的文件夹结构)!
Hope this helps!
希望这可以帮助!

You'll have to search for a file named
postgresql.confinstead ofpostgresql.config(which is wrong and you'll never find this file on your configured PostgreSQL server), which is generally found under the/datafolder of your PostgreSQL installation (and exactly the folder structure that you've shared in your question's screenshot earlier)!您必须搜索名为postgresql的文件。conf代替postgresql。config(这是错误的，你永远不会在你配置的PostgreSQL服务器上找到这个文件)，它通常是在PostgreSQL安装的/data文件夹下找到的(以及之前在你的问题截图*享的文件夹结构)!
Hope this helps!
