kc@example.com (kc kim) — Thu, 17 Aug 2017 10:31:25 +0900

This article explains how to download and install PostgreSQL. As of March 2020, the latest version is PostgreSQL 12.2. This time, PostgreSQL is installed on Windows 10 64-bit.

Download PostgreSQL

Download PostgreSQL from the following URL.

https://www.postgresql.org/

Click Download at the top of the screen.

Click the “Windows” link under Binary packages.

The download page for Windows is displayed. Click the “Download the installer” link.

A screen where you can download each version is displayed. Since PostgreSQL 12.2 Windows x86-64 is used here, click Download in that row.

The download will then start. Save the file in an appropriate location.

Install PostgreSQL

Next, install PostgreSQL. Double-click the downloaded postgresql-12.2-1-windows-x64.exe file, and the following window is displayed. Click Next.

Specify the installation location. You can leave the default as is, or specify another installation directory if you want to change it. Here, the default location is used. Click Next.

Select the components to install. Here, leave everything checked and click Next.

Specify the directory where generated data, such as databases, will be stored. If you want to change it, specify another directory. This time, the default is used again. Click Next.

Set the password for the postgres superuser account. Enter the password twice for confirmation. When the setting is complete, click Next.

Specify the port number used to connect to PostgreSQL. The default 5432 is usually fine, but you can change it. When the setting is complete, click Next.

Specify the locale to use when creating the new database cluster. It is initially set to [Default locale]. Select Korean, Korea, and click Next.

Review the settings so far. Click Next.

Perform the final check before installation. If everything is ready, click Next.

When installation begins, the installation files are created.

When the following screen appears, PostgreSQL installation is complete.

If you click Finish while the checkbox on the left of Stack Builder is selected, Stack Builder starts so that additional applications such as drivers can be installed. This will not be used here, so clear the checkbox and click Finish.

PostgreSQL | Installing PostgreSQL | PATH Settings

kc@example.com (kc kim) — Thu, 17 Aug 2017 10:31:25 +0900

When connecting to PostgreSQL from Command Prompt, setting PATH is convenient. This article explains how to configure PATH.

Configure PATH

The PostgreSQL programs that are run from the command line are included in the bin directory under the PostgreSQL installation directory.

C:\Program Files\PostgreSQL\12\bin>dir/w

C:\Program Files\PostgreSQL\12\bin>

Now configure PATH. This example uses Windows 10.

First, open File Explorer, select “This PC”, and right-click it.

When the “System” screen appears, click “Advanced system settings” in the left menu.

When the “System Properties” screen appears, click “Environment Variables” near the bottom.

The “Edit environment variable” screen is displayed. Configure PATH on this screen.

In “System variables”, find the variable named “Path”. Select the row labeled “Path” and click the “Edit” button.

The “Edit environment variable” screen appears.

Click “New” in the upper right to add a new item to the end of the list on the left. Enter the PostgreSQL bin directory, such as C:\Program Files\PostgreSQL\12\bin. Enter the path that matches your installed PostgreSQL directory. When you are done, click “OK”.

This completes adding the PATH used for PostgreSQL to the PATH setting.

Check Whether PATH Is Set Correctly

Now check whether the setting is correct. After setting PATH, the setting is not applied unless you open a new Command Prompt, so open a new Command Prompt. Then run the following command.

$ psql --version

C:\>psql --version
psql (PostgreSQL) 12.2

C:\>

If the PostgreSQL version is displayed, PATH is set correctly.

If the following message appears, PATH is not set correctly, so check the setting again.

C:\>psql --version
'psql'은(는) 내부 또는 외부 명령, 실행할 수 있는 프로그램, 또는
배치 파일이 아닙니다.

C:\>

This article explained how to configure PATH so PostgreSQL can be used from the command line.

PostgreSQL | Installing PostgreSQL | Start and Stop the Windows Service

kc@example.com (kc kim) — Thu, 17 Aug 2017 10:31:25 +0900

When PostgreSQL is installed in a Windows environment, it is automatically registered as a Windows service and set to a “running” state. This article explains how to check how PostgreSQL is registered as a Windows service, and how to stop or restart PostgreSQL.

Check the Windows Service List

First, check whether PostgreSQL is registered as a Windows service. To display the Windows service list, right-click the Start menu at the lower left of the desktop, and click “Computer Management” from the displayed menu.

When the “Computer Management” screen is displayed, click “Services” under “Services and Applications” in the left menu. Information about services is displayed. In the displayed list, find “postgresql-x64-12” and double-click it.

The properties for PostgreSQL registered as a Windows service are displayed as shown below.

Start and Stop the PostgreSQL Service

Because “Startup type” is set to “Automatic”, PostgreSQL starts automatically as a service when Windows starts. If you want to start PostgreSQL manually, change “Startup type” to “Manual”.

To stop PostgreSQL, click “Stop” under “Service status”.

To start a stopped PostgreSQL service, click “Start” under “Service status”.

In “Path to executable”, you can see the command used to start PostgreSQL.

C:\Program Files\PostgreSQL\12\bin\pg_ctl.exe" runservice -N "postgresql-x64-12" -D "C:\Program Files\PostgreSQL\12\data" -w
