Time Narration
00:01 Welcome to the Spoken Tutorial on Installation of PostgreSQL.
00:07 In this tutorial, we will learn to install PostgreSQL on Ubuntu Linux OS and Windows operating system.
00:17 We will also learn to connect to PostgreSQL database and set password for the database.
00:25 To record this tutorial, I am using:

Ubuntu Linux 14.04 operating system,

Windows 7 operating system and

a working internet connection.

00:38 To follow this tutorial, you should be familiar with either of the mentioned operating system

and have working knowledge of any programming language.

00:49 PostgreSQL is a relational database management software.
00:54 It is a powerful and most advanced open source database system.
00:59 It runs on various platforms such as Linux, Windows and Mac Operating System.
01:07 First we will see how to install PostgreSQL on Linux.
01:13 Press CTRL + ALT +T keys simultaneously to open the terminal.
01:20 In the terminal window, type: sudo apt hyphen get update and press Enter.

Enter the administrative password if prompted.

01:34 This command will update the Ubuntu's default repositories.

Wait until it finishes all the updates.

01:43 Press Ctrl L to clear the screen.
01:47 Next, type: sudo apt hyphen get install postgresql and press Enter.
01:59 We can see the installation process has begun.
02:03 Press 'Y' wherever there is a prompt to confirm the configuration.
02:09 Installation will take sometime to complete, depending upon your internet speed.
02:15 Now we can see that the installation has been completed successfully.

Press Ctrl + L to clear the screen.

02:25 By default, a user account called postgres is created during installation.

But there is no password set for this user account.

02:37 To set the password, type: sudo hyphen u postgres psql postgres and press Enter.
02:49 Enter your system password if prompted.

Notice that the prompt has changed to postgres equal to hash.

02:59 At the prompt, type: slash password postgres.
03:05 Immediately you will be prompted to set a new password for the Postgres user.

I'll enter the password as 'postgres'.

03:15 You can enter a password of your choice.
03:19 Enter the same password one more time.
03:23 Please remember this password for future use.
03:27 Next, type: select version open bracket close bracket semicolon and press Enter.
03:36 Do not forget to put the semicolon at the end of each statement.
03:41 The PostgreSQL version that we have installed now, is displayed on the terminal.
03:47 This indicates that we have successfully installed PostgreSQL.
03:52 I have increased the terminal font size for this demo.

Hence the output is seen in a different window.

04:00 So, I’ll hit the ‘q’ key to exit.

You may not require to do so.

04:07 Now let us see how to disconnect from the server.
04:11 Type slash q and press Enter to disconnect from the server.
04:17 Notice that we are back at the command prompt of the terminal.
04:23 Every time when you want to work with PostgreSQL, you need to be connected to the server.
04:29 Psql is an interactive terminal program provided by PostgreSQL.
04:35 Using psql tool, we can execute SQL statements, manage database objects etc.,
04:44 Another way to connect to a database is using pgAdmin GUI application.
04:51 We can interact with PostgreSQL database server through this interface.
04:57 We will be demonstrating all features using pgAdmin in this series.
05:03 Switch back to terminal.

Let us again connect to the postgreSQL database from the command line.

05:11 For this, type sudo psql hyphen capital U postgres hyphen h localhost hyphen capital W

and press Enter to connect to the server.

05:29 hyphen h is the hostname or IP of the local server.
05:35 Enter the password for postgres user which you have set after installation.
05:41 We can see the prompt changes to Postgres.

Press Ctrl + L to clear the screen.

05:49 Let us verify the PostgreSQL database and whether the server has been started by a simple query.
05:57 Type, Select current underscore user, now();
06:05 We can see the user name and current date as output.

Hit ‘q’ key to exit.

06:13 During installation, some sample databases are created automatically.

Let us have a look at them.

06:21 Type slash list or slash l and press Enter.
06:28 We can see the below database names that are available in PostgreSQL server by default.

Hit ‘q’ key to exit.

06:38 To change a database, type slash c database name.
06:45 I will type ' slash c postgres

Then type the postgres password.

06:54 We can see a message saying ' You are now connected to database “postgres” as user “postgres”
07:02 We can create our own database and tables as per our requirement.
07:08 All the database commands can be executed from the command line.
07:13 Type 'slash q' to disconnect from the server.
07:17 Now let us see how to install PgAdmin.
07:21 PgAdmin can be installed by using any one of the following methods on Ubuntu Linux Operating System.
07:30 Go to Ubuntu Software Centre or Synaptic Package manager, search for PgAdmin and install.
07:39 For more details, refer to the ‘Linux’ spoken tutorials on our website.
07:45 Or in the Terminal, type - sudo apt hyphen get install pgadmin3 and press Enter
07:56 I have already installed PgAdmin in my machine.

I'll show how to open PgAdmin.

08:03 Click Dash Home on the top left corner of the desktop.
08:08 In the Search box, type PgAdmin.
08:12 The PgAdmin icon appears. Click on it.
08:17 The PgAdmin interface opens.
08:21 Now let us learn to install PostgreSQL on Windows OS.
08:28 Open your web browser and go to www.postgresql.org/download

Click on the Windows link.

08:41 Then, click on the Download the graphical installer link.
08:46 I have installed postgres version 9.3.x in Linux Operating System.
08:53 Now I would like to install the same version in Windows also.

You can also install the latest stable version.

09:02 So click on the Previous supported versions and look for version 9.3.x
09:09 Click the link near to the Windows icon.
09:13 It will open a dialog box to save the file.

Click on the Save File button.

09:20 It will take sometime to download the file. Wait until it is finished.
09:25 I have already downloaded it in my machine in the Downloads folder.
09:30 Go to the Downloads folder and double-click on the downloaded file. It will open a window.
08:37 Click on the Run button.
08:40 In the setup window, click on the Next button.
09:44 Select the components and click on the Next button.

In the Installation directory, click on the Next button.

09:52 Enter the password for postgres and re-type one more time. Click on the Next button.
10:00 Installation has started. Wait until it finishes completely.
10:06 Next click on the Finish button to complete the installation.
10:11 Lastly, exit from the wizard.
10:15 Let us see how to open the PostgreSQL command line on Windows.
10:20 Click on Start, then All program then PostgreSQL and psql to open the command line.
10:30 We can see the postgres prompt.
10:33 Type select version() semicolon and press Enter to see the installed version of postgresql.
10:42 This indicates that we have successfully installed in Windows.

Close the window.

10:49 Let us open the PgAdmin from Windows.
10:53 Click on Start, then All program then PostgreSQL and PgAdmin3 to open the GUI interface.
11:04 With this, we come to the end of this tutorial. Let us summarize.
11:09 In this tutorial, we have learnt to install PostgreSQL on Ubuntu Linux and Windows operating systems.
11:18 As an assignment, Connect to the server and list the default available database

Change to anyone of the available database
