Quick question: Why aren't you using the .NET data provider?

If you're set on using ODBC, try using the Microsoft data link properties:

1. Create a file, call it postgresql.udl (make sure its NOT postgresql.udl.txt)
2. Double click on it.
3. Set your connection options.
4. Click OK.
5. Open with Notepad. There you'll find a connection string.
