2] Run the PostgreSQL installer to install Postgres on your computer
Now that we have the installation media for PostgreSQL, let us now go ahead and run the installer. We recommend you go through the entire guide mentioned below and not skip anything.
First of all, open the File Explorer, navigate to the Download folder, and run the installation media. It will trigger the PostgreSQL installation, and you will see the Setup wizard, where you need to click on Next.
You will be asked to specify a directory where you need the application to get installed, most go with the default option, but since I don’t have enough space in my C drive, I will install it in the D drive. If you too, want to change the directory, just click on the Browse icon and change the default location.
Next up, we need to select the components we need to install. The more components you wish to install the more space it will take. Depending on your needs, you may choose to skip using Stack Builder, which is a graphical interface that simplifies the process of downloading and installing modules that complement your PostgreSQL installation. However, do not uncheck the other. We are going to install all of them.
Now, you need to select the directory where you want to store all your data. Based on what you intend to do on your database, select a local storage directory. By default, the data folder will be located inside the directory you intend to install PostgreSQL in, however, it can be altered. To change the directory, click on the Browse icon, navigate to the location where you want to store your data, and select a folder. Once done, click on Next.
Set a password of your choice, since it is a local DB, there are no rules that you need to adhere to. Just pick a number that you can easily remember and click on Next.
Now, enter the port number if you have one, or leave it to the default number and click on Next. Then, you will be asked to select a language and location, do that from the Locale drop-down menu, and click on Next.
Finally, go through the summary, once satisfied, click on Next and then start the installation process. It might take some time, so, wait for the installation to complete and then move to the next step.
