Postgresql скачать для windows 10 как установить

In this tutorial, you’ll learn how to install PostgreSQL 14.7 on Windows 10.

The process is straightforward and consists of the following steps:

Install PostgreSQL
Configure Environment Variables
Verify the Installation
Download the Northwind PostgreSQL SQL file
Create a New PostgreSQL Database
Import the Northwind SQL file
Verify the Northwind database installation
Connect to the Database Using Jupyter Notebook

Prerequisites

A computer running Windows 10
Internet connection

Download the official PostgreSQL 14.7 at https://get.enterprisedb.com/postgresql/postgresql-14.7-2-windows-x64.exe
Save the installer executable to your computer and run the installer.

Note: We recommend version 14.7 because it is commonly used. There are newer versions available, but their features vary substantially!

Step 1: Install PostgreSQL

We’re about to initiate a vital part of this project — installing and configuring PostgreSQL.

Throughout this process, you’ll define critical settings like the installation directory, components, data directory, and the initial ‘postgres’ user password. This password grants administrative access to your PostgreSQL system. Additionally, you’ll choose the default port for connections and the database cluster locale.

Each choice affects your system’s operation, file storage, available tools, and security. We’re here to guide you through each decision to ensure optimal system functioning.

In the PostgreSQL Setup Wizard, click Next to begin the installation process.
Accept the default installation directory or choose a different directory by clicking Browse. Click Next to continue.
Choose the components you want to install (e.g., PostgreSQL Server, pgAdmin 4 (optional), Stack Builder (optional), Command Line Tools),no characters will appear on the screen as you type your password and click Next.
Select the data directory for storing your databases and click Next.
Set a password for the PostgreSQL “postgres” user and click Next.
- There will be some points where you’re asked to enter a password in the command prompt. It’s important to note that for security reasons, as you type your password, no characters will appear on the screen. This standard security feature is designed to prevent anyone from looking over your shoulder and seeing your password. So, when you’re prompted for your password, don’t be alarmed if you don’t see any response on the screen as you type. Enter your password and press ‘Enter’. Most systems will allow you to re-enter the password if you make a mistake.
- Remember, it’s crucial to remember the password you set during the installation, as you’ll need it to connect to your PostgreSQL databases in the future.
Choose the default port number (5432) or specify a different port, then click Next.
Select the locale to be used by the new database cluster and click Next.
Review the installation settings and click Next to start the installation process. The installation may take a few minutes.
Once the installation is complete, click Finish to close the Setup Wizard.

Step 2: Configure Environment Variables

Next, we’re going to configure environment variables on your Windows system. Why are we doing this? Well, environment variables are a powerful feature of operating systems that allow us to specify values — like directory locations — that can be used by multiple applications. In our case, we need to ensure that our system can locate the PostgreSQL executable files stored in the «bin» folder of the PostgreSQL directory.

By adding the PostgreSQL «bin» folder path to the system’s PATH environment variable, we’re telling our operating system where to find these executables. This means you’ll be able to run PostgreSQL commands directly from the command line, no matter what directory you’re in, because the system will know where to find the necessary files. This makes working with PostgreSQL more convenient and opens up the possibility of running scripts that interact with PostgreSQL.

Now, let’s get started with the steps to configure your environment variables on Windows!

On the Windows taskbar, right-click the Windows icon and select System.
Click on Advanced system settings in the left pane.
In the System Properties dialog, click on the Environment Variables button.
Under the System Variables section, scroll down and find the Path variable. Click on it to select it, then click the Edit button.
In the Edit environment variable dialog, click the New button and add the path to the PostgreSQL bin folder, typically C:\\Program Files\\PostgreSQL\\14\\bin.
Click OK to close the «Edit environment variable» dialog, then click OK again to close the «Environment Variables» dialog, and finally click OK to close the «System Properties» dialog.

Step 3: Verify the Installation

After going through the installation and configuration process, it’s essential to verify that PostgreSQL is correctly installed and accessible. This gives us the assurance that the software is properly set up and ready to use, which can save us from troubleshooting issues later when we start interacting with databases.

If something went wrong during installation, this verification process will help you spot the problem early before creating or managing databases.

Now, let’s go through the steps to verify your PostgreSQL installation.

Open the Command Prompt by pressing Win + R, typing cmd, and pressing Enter.
Type psql --version and press Enter. You should see the PostgreSQL version number you installed if the installation was successful.
To connect to the PostgreSQL server, type psql -U postgres and press Enter.
When prompted, enter the password you set for the postgres user during installation. You should now see the postgres=# prompt, indicating you are connected to the PostgreSQL server.

Step 4: Download the Northwind PostgreSQL SQL File

Now, we’re going to introduce you to the Northwind database and help you download it. The Northwind database is a sample database originally provided by Microsoft for its Access Database Management System. It’s based on a fictitious company named «Northwind Traders,» and it contains data on their customers, orders, products, suppliers, and other aspects of the business. In our case, we’ll be working with a version of Northwind that has been adapted for PostgreSQL.

The following steps will guide you on how to download this PostgreSQL-compatible version of the Northwind database from GitHub to your local machine. Let’s get started:

First, you need to download a version of the Northwind database that’s compatible with PostgreSQL. You can find an adapted version on GitHub. To download the SQL file, follow these steps:

Open your Terminal application.
Create a new directory for the Northwind database and navigate to it:

mkdir northwind && cd northwind
Download the Northwind PostgreSQL SQL file using curl:

curl -O <https://raw.githubusercontent.com/pthom/northwind_psql/master/northwind.sql>

This will download the northwind.sql file to the northwind directory you created.

Step 5: Create a New PostgreSQL Database

Now that we’ve downloaded the Northwind SQL file, it’s time to prepare our PostgreSQL server to host this data. The next steps will guide you in creating a new database on your PostgreSQL server, a crucial prerequisite before importing the Northwind SQL file.

Creating a dedicated database for the Northwind data is good practice as it isolates these data from other databases in your PostgreSQL server, facilitating better organization and management of your data. These steps involve connecting to the PostgreSQL server as the postgres user, creating the northwind database, and then exiting the PostgreSQL command-line interface.

Let’s proceed with creating your new database:

Connect to the PostgreSQL server as the postgres user:

psql -U postgres
Create a new database called northwind:

postgres-# CREATE DATABASE northwind;
Exit the psql command-line interface:

postgres-# \\q

Step 6: Import the Northwind SQL File

We’re now ready to import the Northwind SQL file into our newly created northwind database. This step is crucial as it populates our database with the data from the Northwind SQL file, which we will use for our PostgreSQL learning journey.

These instructions guide you through the process of ensuring you’re in the correct directory in your Terminal and executing the command to import the SQL file. This command will connect to the PostgreSQL server, target the northwind database, and run the SQL commands contained in the northwind.sql file.

Let’s move ahead and breathe life into our northwind database with the data it needs!

With the northwind database created, you can import the Northwind SQL file using psql. Follow these steps:

In your Terminal, ensure you’re in the northwind directory where you downloaded the northwind.sql file.
Run the following command to import the Northwind SQL file into the northwind database:

psql -U postgres -d northwind -f northwind.sql

This command connects to the PostgreSQL server as the postgres user, selects the northwind database, and executes the SQL commands in the northwind.sql file.

Step 7: Verify the Northwind Database Installation

You’ve successfully created your northwind database and imported the Northwind SQL file. Next, we must ensure everything was installed correctly, and our database is ready for use.

These upcoming steps will guide you on connecting to your northwind database, listing its tables, running a sample query, and finally, exiting the command-line interface. Checking the tables and running a sample query will give you a sneak peek into the data you now have and verify that the data was imported correctly. This means we can ensure everything is in order before diving into more complex operations and analyses.

To verify that the Northwind database has been installed correctly, follow these steps:

Connect to the northwind database using psql:

psql -U postgres -d northwind
List the tables in the Northwind database:

postgres-# \\dt

You should see a list of Northwind tables: categories, customers, employees, orders, and more.
Run a sample query to ensure the data has been imported correctly. For example, you can query the customers table:

postgres-# SELECT * FROM customers LIMIT 5;

This should return the first five rows from the customers table.
Exit the psql command-line interface:

postgres-# \\q

Congratulations! You’ve successfully installed the Northwind database in PostgreSQL using an SQL file and psql.

Step 8: Connect to the Database Using Jupyter Notebook

As we wrap up our installation, we will now introduce Jupyter Notebook as one of the tools available for executing SQL queries and analyzing the Northwind database. Jupyter Notebook offers a convenient and interactive platform that simplifies the visualization and sharing of query results, but it’s important to note that it is an optional step. You can also access Postgres through other means. However, we highly recommend using Jupyter Notebook for its numerous benefits and enhanced user experience.

To set up the necessary tools and establish a connection to the Northwind database, here is an overview of what each step will do:

!pip install ipython-sql: This command installs the ipython-sql package. This package enables you to write SQL queries directly in your Jupyter Notebook, making it easier to execute and visualize the results of your queries within the notebook environment.
%load_ext sql: This magic command loads the sql extension for IPython. By loading this extension, you can use the SQL magic commands, such as %sql and %%sql, to run SQL queries directly in the Jupyter Notebook cells.
%sql postgresql://postgres@localhost:5432/northwind: This command establishes a connection to the Northwind database using the PostgreSQL database system. The connection string has the following format:

postgresql://username@hostname:port/database_name

In this case, username is postgres, hostname is localhost, port is 5432, and database_name is northwind. The %sql magic command allows you to run a single-line SQL query in the Jupyter Notebook.
Copy the following text into a code cell in the Jupyter Notebook:

!pip install ipython-sql
%load_ext sql
%sql postgresql://postgres@localhost:5432/northwind

On Windows you may need to try the following command because you need to provide the password you set for the “postgres” user during installation:

%sql postgresql://postgres:{password}@localhost:5432/northwind

Bear in mind that it’s considered best practice not to include sensitive information like passwords directly in files that could be shared or accidentally exposed. Instead, you can store your password securely using environment variables or a password management system (we’ll link to some resources at the end of this guide if you are interested in doing this).
Run the cell by either:
- Clicking the «Run» button on the menu bar.
- Using the keyboard shortcut: Shift + Enter or Ctrl + Enter.
Upon successful connection, you should see an output similar to the following:

'Connected: postgres@northwind'

This output confirms that you are now connected to the Northwind database, and you can proceed with the guided project in your Jupyter Notebook environment.

Once you execute these commands, you’ll be connected to the Northwind database, and you can start writing SQL queries in your Jupyter Notebook using the %sql or %%sql magic commands.

Next Steps

Based on what you’ve accomplished, here are some potential next steps to continue your learning journey:

Deepen Your SQL Knowledge:
- Try formulating more complex queries on the Northwind database to improve your SQL skills. These could include joins, subqueries, and aggregations.
- Understand the design of the Northwind database: inspect the tables, their relationships, and how data is structured.
Experiment with Database Management:
- Learn how to backup and restore databases in PostgreSQL. Try creating a backup of your Northwind database.
- Explore different ways to optimize your PostgreSQL database performance like indexing and query optimization.
Integration with Python:
- Learn how to use psycopg2, a popular PostgreSQL adapter for Python, to interact with your database programmatically.
- Experiment with ORM (Object-Relational Mapping) libraries like SQLAlchemy to manage your database using Python.
Security and Best Practices:
- Learn about database security principles and apply them to your PostgreSQL setup.
- Understand best practices for storing sensitive information, like using .env files for environment variables.
- For more guidance on securely storing passwords, you might find the following resources helpful:
  - Using Environment Variables in Python

What is PostgreSQL?

PostgreSQL is a free object-relational database management system (DBMS). PostgreSQL is implemented for many operating systems such as: BSD, Linux, macOS, Solaris and Windows.

PostgreSQL uses the PL/pgSQL language.

PL/pgSQL is a procedural extension of the SQL language, developed and used in PostgreSQL DBMS.

PL/pgSQL language is designed to create functions, triggers, it adds control structures to SQL language, and it helps us to perform complex calculations.

PostgreSQL is one of the most popular database management systems (TOP 5 popular database management systems).

At the time of writing, the most up-to-date version of PostgreSQL 12 is the one we will be installing.

System requirements for PostgreSQL 12 installation on Windows

PostgreSQL 12 can not be installed on all versions of Windows, in particular, the following versions are officially supported and only 64-bit:

Windows Server 2012 R2;
Windows Server 2016;
Windows Server 2019.

As you can see, there’s no Windows 10 on the official list, but installation on this system goes smoothly, as does subsequent PostgreSQL functioning.

In addition, there are other requirements:

Processor with at least 1 GHz;
2 gigabytes of RAM;
At least 512 megabytes of free disk space (more for installing additional components is recommended);
It is also recommended that all Windows operating system updates be installed.

Installing PostgreSQL 12 and pgAdmin 4 on Windows 10

So let’s move on to the installation process and look at all the steps that need to be followed in order to install PostgreSQL 12 and pgAdmin 4 on Windows 10.

Step 1 – Downloading the installer for Windows

As mentioned earlier, PostgreSQL is implemented for many platforms, but since we will be installing PostgreSQL on Windows, we need a Windows installer accordingly. You can of course download this distribution from the official PostgreSQL website, here is the download page – https://www.postgresql.org/download/windows/.

After going to the page you need to click on the link “Download the installer”, as a result you will be taken to the site of EnterpriseDB, which prepares graphical distributions of PostgreSQL for many platforms, including Windows, so you can immediately go to this site, here is the link to the download page https://www.enterprisedb.com/downloads/postgres-postgresql-downloads.

Here you need to select the PostgreSQL version and platform, in our case choose PostgreSQL 12 and Windows x86-64.

As a result, you should download the file postgresql-12.2-2-windows-x64.exe with the size of about 191 Mbytes (version 12.2-2 is available at the time of writing).

Step 2 – Starting the PostgreSQL installer

Now in order to start the installation you need to run the downloaded file (PostgreSQL installation requires administrator rights).

After the launch, a welcome screen will open, click “Next”.

Step 3 – Specify the directory to install PostgreSQL 12

Next, if necessary, we can specify the path to the directory where we want to install PostgreSQL 12, but we can leave it by default. Click “Next”.

Step 4 – Choose components for installation

Then select the components that we need to install, to do this we leave the checkboxes for the components that we need, and be sure we need PostgreSQL Server and pgAdmin 4.

You can install the command line utilities and Stack Builder on your own, i.e. you can not install them. Press “Next.”

Step 5 – Specify a directory to store database files

On this step, we need to specify the directory where the database files will be located by default.

In the case of a test installation, for example, for training, you can leave it by default, but “combat” databases should always be stored in a separate location, so if you plan to use the PostgreSQL server for some other purposes, it is better to specify a separate disk.

Click “Next”.

Step 6 – Set a password for the postgres system user

Next we need to set a password for a postgres user – this is a PostgreSQL Server administrator with maximum rights.

We enter and confirm the password. Click “Next”.

Step 7 – Specify the port for your PostgreSQL instance

On this step, if necessary, we can change the port on which PostgreSQL Server will work, if you do not have such a need, then leave it by default.

Click “Next”.

Step 8 – Specify the encoding in the database

Then we can specify a specific data encoding in the database, for this purpose we need to select the desired Locale from the drop-down list.

However, you can also leave it by default by clicking “Next”.

Step 9 – Checking PostgreSQL installation parameters

Everything is ready for installation, at this step we check the parameters we entered earlier and if everything is correct, i.e. everything we entered, we press “Next”.

Step 10 – Start the installation process

Next you will see another additional window where we must click “Next” to start the PostgreSQL installation process on your computer.

The installation has begun, it will last literally one minute.

Step 11 – Finishing the installation

When the “Completing the PostgreSQL Setup Wizard” message window is displayed, the installation of PostgreSQL 12, pgAdmin 4 and other components will be completed.

Also in this window we will be offered to run Stack Builder to download and install additional components, if you do not need it, then uncheck “Lanch Stack Builder at exit?

Click “Finish”.

Run and configure pgAdmin 4

PostgreSQL 12 and pgAdmin 4 we have installed, now let’s start pgAdmin 4, connect to the server and configure the pgAdmin work environment.

To start pgAdmin 4, go to the start menu, find PostgreSQL 12 and pgAdmin 4 in it.

Connecting to the PostgreSQL 12 server

pgAdmin 4 has a web interface, so as a result you should run your browser and open the pgAdmin 4 application.

The first time you start pgAdmin 4, you will see a “Set Master Password” window, where we must set a “master password”, this may not be done, but if we save the user’s password (“Save password” checkbox), for example, so that every time you connect you do not need to enter it, it is strongly recommended to invent and specify an additional password here, it is done once.

Enter it and click “OK”.

To connect to the newly installed local PostgreSQL server in the server browser, click on “PostgreSQL 12”.

The “Connect to Server” window will start, where you need to enter the password of the postgres system user, i.e. this is the password that you invented when you installed PostgreSQL.

Enter the password, tick “Save Password” to save the password and each time you do not enter it (thanks to the “master password” functionality, all passwords saved in this way will be additionally encrypted).

Click on “OK”.

As a result you will connect to the local PostgreSQL 12 server and see all the objects that are located on this server.

In order to make sure that our PostgreSQL server is running, let’s write a simple SELECT query that will show us the PostgreSQL server version.

To write SQL queries in pgAdmin 4, you can use Query Tool or Russian “Query”, you can run it using the icon on the panel or from the menu “Tools”.

After you open the Query Tool, write.

SELECT VERSION()

This query shows the PostgreSQL version. As you can see, everything works!
