windows - 移动 pgdata 目录后，Postgres 服务将无法在 Windows 中启动

Question

我关注了these instructions将 Postgres 数据目录从 C:\Users\username\Documents\dir\postgres96_data 移动到 C:\Users\username\Documents\postgres96_data。

现在 Postgres 服务将无法启动。尝试手动启动它会产生以下消息(从 pt-br 自由翻译):

"The postgres-x64-9.6 service on Local Computer started then stopped. Some services stop automatically if they are not beeing used by other services or programs."

我尝试(成功)使用命令在 cmd.exe 中启动数据库

"C:\Program Files\PostgreSQL\9.6\bin\pg_ctl.exe" start -D "C:\Users\username\Documents\postgres96_data" -w

Answer 1

您需要更改服务定义。该服务仍在使用旧的数据目录。

要更改服务，请将其删除并重新创建:

pg_ctl unregister -N postgres-x64-9.6

然后使用新的数据目录重新创建它:

pg_ctl register -N postgres-x64-9.6 -D "C:\Users\username\Documents\postgres96_data"

这假设您使用的是默认安装，其中服务使用内置“网络帐户”运行。如果不是这种情况，您需要在注册服务时使用 -U 和 -P 参数提供必要的用户名和密码。
