[windows] Setting Windows PATH for Postgres tools

configuring postreSQL PATH variable on Windows 7

I encountered this issue too. I'm using Git Bash, hence the Unix-style $ prompt on Windows.

$ rails db
Couldn't find database client: psql, psql.exe.  Check your $PATH and try again.

Here's what I did:

In Windows 7, navigate to:

Control Panel
  All Control Panel Items
    System
      Advanced System Settings
        Environment Variables
          from the System Variables box select "PATH"
              Edit...

Then append this string to the existing PATH Variable Value:

;C:\Program Files\PostgreSQL\9.2\bin

and click "OK" three times to exit the menus.

Now, close the console and restart it.

Navigate back to the directory of your Rails app. In my case, this is accomplished with:

$ cd rails_projects/sample_app

Then, try again:

$ rails db
