Best PostgreSQL Courses for Beginners

So you want to learn PostgreSQL but aren't sure how to get started? In this article, we look at some of the best online courses available on the Internet for learning PostgreSQL, so you can get started right away!

What Is PostgreSQL?

PostgreSQL is used in major companies such as Apple and Instagram. You may be wondering: should I learn PostgreSQL?

PostgreSQL is a popular dialect of SQL, or Structured Query Language, a programming language for accessing and managing data in relational databases. These relational databases store information in a structured manner. The information in these databases is organized neatly into tables, which are linked or related to one another using keys. Each table contains a collection of records, and each record contains a set of fields.

Well, here at, we have a learning path that takes you from a complete beginner with no programming experience to a PostgreSQL master with SQL from A to Z in PostgreSQL. We’ll explore some of the courses in this learning path later in this article.

What Is an SQL Dialect?

We've mentioned PostgreSQL is an SQL dialect, but what exactly is an SQL dialect? SQL, like human languages, has several dialects. Human language dialects differ in how words are pronounced or used, whereas SQL dialects differ in the syntax and keywords used to write queries and other commands.

SQL dialects exist because databases differ greatly in how they store and manage data. Adjusting the SQL syntax to create a dialect allows developers to write code that is specific to the features and capabilities of a particular database system. If you want to find out more about SQL databases, check out our article “The Most Popular Databases in 2023.”

The following are some of the most common SQL dialects you may have already encountered.

1. PostgreSQL

This dialect is used with PostgreSQL databases. It has many features, including user-defined functions, triggers, and stored procedures.

2. MySQL

This dialect Is used with MySQL databases. It comes with several features, such as stored procedures and triggers, used to create more efficient and powerful database applications. Have you worked with MySQL before and want to make a change to PostgreSQL? Check out our article “PostgreSQL vs. MySQL: Is Switching Difficult?” on how to make that change.

3. Transact-SQL (T-SQL)

This is the dialect used with Microsoft SQL Server and Sybase ASE. It has many features, including stored procedures, triggers, cursors, and extended programming capabilities.


You find this dialect of SQL in Oracle databases. It allows developers to create powerful and efficient database applications. It has many features, including exception handling, object-oriented programming, and embedded SQL.

Where Did PostgreSQL Come From?

PostgreSQL was created at the University of California, Berkeley by a group of developers led by Michael Stonebraker. It was developed as an open-source alternative to commercial database systems, which had become costly and difficult to use. The primary goal was to create something powerful, dependable, and extensible while remaining user-friendly.

Since its initial release in 1996, PostgreSQL has been continuously developed and improved. It is now one of the most popular database systems in the world. Find out more about the history of PostgreSQL in our article “Breaking With Filing Cabinets: The History of PostgreSQL.”

Why Should I Learn PostgreSQL?

PostgreSQL is powerful yet easy to use for various tasks, from data manipulation and retrieval to data definition and access control. It is used by many major organizations, including Apple, Instagram, and Spotify. See our article Which Major Companies Use PostgreSQL? What Do They Use It for?” to learn more about the businesses that use it.

Best PostgreSQL Courses for Beginners

Let's look at some of the reasons why you should learn PostgreSQL.

1. In-Demand Skill

As previously stated, PostgreSQL is used by major corporations. Learning PostgreSQL leads you to a variety of exciting opportunities. Check out our article “Database Jobs to Choose in 2023” to see where your PostgreSQL skills may be put to use.

2. Open Source

Because PostgreSQL is an open-source database, it is free to use and modify. This makes it ideal for developers looking for a low-cost way to build applications.

3. Performance

PostgreSQL is well-known for its speed and dependability. It can handle heavy workloads and has features like multiversion concurrency control (MVCC) to ensure consistent performance even when there are many concurrencies.

4. Security

PostgreSQL has several security features including row-level security, SSL, and encryption at rest. As a result, it is ideal for sensitive data applications.

5. Scalability

PostgreSQL is highly scalable and capable of handling large amounts of data. It includes table partitioning, which can greatly improve scalability.
