Proper way of recovering a Postgres database from a PGdata folder?

Question

My PC has its OS reinstalled recently. I'm left with the PGdata folder of a Postgres server that was locally hosted.

Could anyone explain how to recover all the data therein? My first intuition was to start a new server and replace its new PGdata folder with the old one but this seems somewhat barbaric.

只要PostgreSQL版本，操作系统和机器体系结构匹配，您就可以简单地针对现有数据目录启动PostgreSQL：

pg_ctl start -D /path/to/your/data
