Downloading and Installing PostgresSQL:

Part 1: Downloading & Installing PostgresSQL

1. Go to http://www.postgresql.org/
2. In the search engine at the top right hand corner copy & paste postgresql-8.1.9-1.zip and press enter. You can also install newer patches like postgresql-8.1.11-1.zip but stay within the postgresql-8.1 versions unless you want to modify the Visual C++ project to point to the new locations.
3. Click the one pointed to you by the red arrow
   
   if not included, look for something similar, keeping in mind you need the postgresql-8.1.9-1.zip)
4. Click on the link shown to you by the red arrow; "postgresql-8.2.5-1.zip"
   
5. Find the flag of the country you are in, and click the Ftp link under the flag.
6. Now a window will pop up asking whether you want to save or run the installation program. Save it in your download folder, if you haven't created one do so. The purpose of having a Download file is that every time you download a big file you save it so that you don't have to waste your time finding the file and downloading it again. However with small files, there is no point in saving them because of the small amount of time they take to download.
7. Look in your download folder for postgresql-8.1.9-1.zip
8. Right click on postgresql-8.1.9-1.zip click Extract to postgresql-v8.1.9-1.zip\
9. Go to the folder you just extracted to in your download folder.
10. Double click on the file postgresql-8.1.msi, and to check whether you have the right version, look at the size, is it 134Kb.
11. A window should have popped up, saying what language you want to use in the installation. Select your preferred language. (if you have any other windows close them down and SAVE your work)
12. This window is important, so don't miss any thing out.
    

1. • Scroll down to Database drivers, and click on the small triangle pointing downwards, a small list of options will appear click "Entire feature will be unavailable".
   • Scroll to the very bottom to Development, now just like the other one click on the small triangle pointing downwards and again the options will appear, this time click "Entire feature will be installed on your local driver". Click Next.
2. In the next window type into the User name field any random password, as you will not have to remember it.
