Creating a new database on a new hard drive

[BubbleBoy]

I have postgres9.2\data and HM2-parent with all current databases on D:\
I want a new database with HM2-parent on S:\

The tutorial for moving databases all assume, that I will copy over \data\, which I can't (it's bigger than the target drive). With just a fresh new \data\ and changing the postgres imagepath in registry, the postgres service won't start again.

How can I point postgres to a fresh \data\ path without copying over the old database?

Once I have \data\ on S:\, I assume I can choose the HM2-parent on S:\ when creating a new database.

Thanks.

You would need to install another version of Postgres to have the data folder on different locations, or just delete everything and start again.

Yes, you can choose the parent folder when creating a database.

How does this work, having two different postgreses installed?

When I install a new postgres, how do I reactivate the old? I of course want to be able to use the old database.

By default Postgres is installed to work with port 5432 - and your current installation is set exactly so.
But you can (manually) install another Postgres on port 5433
Theoretically they both can work simultaneously - but this will complicate a life for your PC (more resources will be used).
So in case of two Postgres installations the best way is to have running only one (or another). This is managed via Control panel - Administrative tools - Services - Stop\start service
