PostgreSQL Install-Windows

with 2 comments

A number of folks have asked me to create a post of a PostgreSQL installation on Windows. So, here is my step-by-step PostgreSQL 9.3 installation, and you can go further and learn how to setup your own PostgreSQL database schema.

Download PostgreSQL Database

You can start the download of PostgreSQL from this site. It leads you to the EnterpriseDB site, where you can download the prepackaged software.

Install PostgreSQL 9.3 on Windows

These steps walk you through installing PostgreSQL and the the pgJDBC v9.3, psqlODBC (32 bit), and psqlODBC (64 bit) packages.

PostgreSQL_i01

  1. The first thing you need to do is launch the PostgreSQL file from download folder.

PostgreSQL_i02

  1. After launching the downloaded file, you see an Open File – Security Warning dialog message. Click the Run button to run the PostgreSQL executable file.

PostgreSQL_i03

  1. The first dialog screen is the Setup – PostgreSQL dialog, which welcomes you and prompts you to start the installtion of PostgreSQL. Click the Next button to continue.

PostgreSQL_i04

  1. The Installation Directory dialog sets the location for the PostgreSQL server. Click the Next button to continue.

PostgreSQL_i05

  1. The Data Directory dialog sets the location for the PostgreSQL server’s data repository. Click the Next button to continue.

PostgreSQL_i06

  1. The first Setup dialog sets the database’s superuser password. Click the Next button to continue.

PostgreSQL_i07

  1. The second Setup dialog sets the database’s listener port, which is Port 5432 by default. Click the Next button to continue.

PostgreSQL_i08

  1. The third Setup dialog sets the database’s default Locale. Click the Next button to continue.

PostgreSQL_i09

  1. The Ready to Install dialog lets you start the installation. Click the Next button to continue.

PostgreSQL_i10

  1. The Installing dialog lets you montor the unpacking of programs for the installation. You need not click any buttons to continue.

PostgreSQL_i11

  1. The Completing the PostgreSQL Setup Wizard dialog advises you that you’ve completed the setup. Checking the Stack Builder check box lets you download and install additional tools, drivers, and applications. Click the Next button to continue.

PostgreSQL_i12

  1. This is Welcome dialog to the Stack Builder. Click the Next button to continue.

PostgreSQL_i13

  1. This is dialog lets you select applications that you would like to install. Click the plus symbol for the Database Drivers option to continue.

PostgreSQL_i14

  1. In the modified dialog, click the pgJDBC v9.3, psqlODBC (32 bit), and psqlODBC (64 bit) check boxes. Then, click the Next button to continue.

PostgreSQL_i15

  1. This dialog tells you the pgJDBC v9.3, psqlODBC (32 bit), and psqlODBC (64 bit) installed packages. Click the Next button to continue.

PostgreSQL_i16

  1. This dialog lays a downloading progress bar while loading the additional packages. You don’t need to do anything to continue.

PostgreSQL_i17

  1. This dialog lays a downloading progress bar while loading the additional packages. Click the Next button to continue.

PostgreSQL_i18

  1. The Setup pgJDBC dialog welcomes you to the setup wizard. Click the Next button to continue.

PostgreSQL_i19

  1. The Installation Directory dialog lets you set the pgJDBC installation directory. Click the Next button to continue.

PostgreSQL_i20

  1. The Ready to Install dialog lets you install the pgJDBC package. Click the Next button to install it.

PostgreSQL_i21

  1. The Setup dialog confirms you’ve installed the add-on packages. Click the Finish button to complete the installation.

Configure psqlODBC on Windows

These steps walk you through configuring the psqlODBC packages.

PostgreSQL_i22

  1. The Setup dialog helps you configure the psqlODBC package. Click the Next button to install it.

PostgreSQL_i23

  1. The Installation Directory dialog lets you set the psqlODBC installation directory. Click the Next button to continue.

PostgreSQL_i23

  1. The Ready to Install dialog lets you install the psqlODBC package. Click the Next button to install it.

PostgreSQL_i24

  1. The Ready to Install dialog lets you install the psqlODBC package. Click the Next button to install it.

PostgreSQL_i25

  1. The Installing psqlODBC dialog displays a dialog while installing the psqlODBC package(s). You need not click anything, the dialog dismisses itself when complete.

PostgreSQL_i26

  1. The Installing psqlODBC dialog displays a dialog while installing the psqlODBC package(s). You need not click anything, the dialog dismisses itself when complete.

PostgreSQL_i27

  1. The Stack Builder dialog displays a message that everything is installed. Click the Finish button when complete.

Connect to the Default PostgreSQL database

You have two options for connecting to the PostgreSQL database. One uses the GUI pgAdmin III console and the other uses the command line.

Connect through pgAdmin III to the PostgreSQL Database

PostgreSQL_i27

  1. In Windows, navigate to through the Start to the pgAdmin III menu option.

PostgreSQL_i28

  1. After launching pgAdmin III, you’ll see the pgAdmin II console, displayed at left.

PostgreSQL_i29

  1. Right click on the PostgreSQL 9.3 (localhost:5432) item in the Object browser and click the Connect menu choice from the floating menu.

PostgreSQL_i30

  1. Enter the password you chose when installing the PostgreSQL Server, and click the OK button.

Connect through the Command-line to the PostgreSQL Database

These steps show you how to connect through the PostgreSQL Command Line Interface (CLI) – psql. psql is like Oracle’s sqlplus, MySQL’s mysql, and Microsoft SQL Server’s sqlcmd CLI interfaces. By default, the PostgreSQL binary directory is not in your default %PATH% environment variable, so you need to add it. I recommend an environment file because in a test situation you may not want to use it all the time.

Create the following directory for the environment file:

C:\Data\PostgreSQL\env

You can create an environment file with any text editor or do it at the command line, like this:

COPY CON postgresqlenv.bat
SET PATH=%PATH%;C:\Program Files\PostgreSQL\9.3\bin;.
^Z

Then, you can source the environment file like this:

C:\> postgresql.bat

Now, you can connect to the default database provided you understand that PostgreSQL Stack Builder set some values that differ from the defaults if you installed it manually. Specifically, they set the default value of the database to postgres and default value of the user to postgres.

That means you can connect with the following, provided you remember the password you used during installation:

C:\> psql -d postgres -U postgres

You should see the following when you connect:

C:\> psql -d postgres -U postgres
 Password for user postgres:
psql (9.3.3)
WARNING: Console code page (437) differs from Windows code page (1252)
         8-bit characters might not work correctly. See psql reference
         page "Notes for Windows users" for details.
Type "help" for help.

You can now submit interactive SQL statements or run batch files, like:

postgres=# SELECT 'Hello World!';

It displays:

   ?COLUMN?
--------------
 Hello World!
(1 ROW)

Adding a column alias to the string literal gives a more readable formatted output:

postgres=# SELECT 'Hello World!' AS "String Literal";

It displays:

 String Literal
----------------
 Hello World!
(1 ROW)

PostgreSQL’s CLI Help

You have the ability to do a lot with the PostgreSQL psql CLI. The general command to discover help is help, and it displays the following:

postgres=# help
You are USING psql, the command-line interface TO PostgreSQL.
TYPE:  \copyright FOR distribution terms
       \h FOR help WITH SQL commands
       \? FOR help WITH psql commands
       \g OR terminate WITH semicolon TO EXECUTE query
       \q TO quit

You quit PostgreSQL with a \q command:

postgres=# \q

You can find more help with the \HELP or the \? commands:

\HELP

It displays the following:
