What is PostgreSQL?

A database is a form of online data repository that functions like an application and allows users to store and access data at any time, through any part of the world. One of those databases is PostgreSQL, also known as Postgres. PostgreSQL is significantly new, as compared to its alternatives in the market. There is something different about PostgreSQL because, in this short period, PostgreSQL has outshined its alternatives and emerged as a very promising technology. We will look at the same in the blog further.

Before taking a deeper dive into “What is PostgreSQL?” let’s quickly have a look over the pointers which we will be covering in the blog.

Introduction to PostgreSQL

Introduction to PostgreSQL

PostgreSQL is an open-source, advanced, enterprise-class type of database that works on the concepts of relational SQL-based and non-relational JSON-based databases.

Why do we need PostgreSQL?

Read the below-mentioned pointers to advance through the journey of learning about PostgreSQL.

History of PostgreSQL

Moving up in the series of sub-sections, now it is the time to learn about the roots of PostgreSQL. Below-stated points will tell you about the history of PostgreSQL.

Differences between MySQL and PostgreSQL

This sub-section will let you know about the difference between MySQL and PostgreSQL as both of them possess the same functionalities.

Parameters MySQL PostgreSQL
Open Source The code of MySQL was made public in the open source under the terms of the GNU license. The code of PostgreSQL was made publicly available under a PostgreSQL license similar to that of BSD & MIT licenses.
ACID Property MySQL partially follows ACID properties, for complete compliance should be used with cluster storage engines. PostgreSQL completely follows ACID properties.
SQL Compliance MySQL is partially compliant with SQL. PostgreSQL is completely compliant with SQL.
Performance MySQL is only used for simpler queries, namely for web-based projects and straightforward transactions. PostgreSQL is used for complex queries and covers almost every domain of databases.
JSON Support MySQL supports JSON but does not support the rest of the NoSQL properties. PostgreSQL supports JSON as well as the other properties of NoSQL.
Community It has a large community support but its main focus is on maintaining the existing features. Unlike MySQL, Postgres has large community support which works to enhance the capabilities of PostgreSQL.

Installation of PostgreSQL

Installation of PostgreSQL

In this part of the blog, we will set up the dynamic environment in your system to run PostgreSQL. Moreover, we will also create our first database in PostgreSQL. Follow the below-mentioned steps for the step-by-step installation procedure for PostgreSQL.

Step 1 –

The first step for the installation of any software is to check the prerequisites.

Step 2 –

Go to the website of EDB and download the installation file for Postgres.

Step 3 –

After downloading open the file and click next to proceed and choose a location for installation.

Step 4 –

Select the software components to be installed into the system. Make sure all the options are selected, and click next.

Step 5 –

Select a data directory, leaving everything at default is recommended, and click next.

Step 6 –

Select the master password for your database into the system and select the port, preferably 5432, and click next.

Step 7 –

Now in this step, we will be setting up the default operating system. Leave it by default, and click next.

Step 8 –

The installation process is now completed and ready to use. Now it is time to connect your PostgreSQL with the web.

Step 9 –

Open pgadmin, right-click on servers and then create a server to be used.

Step 10 –

Enter the needed credentials and write a basic command to check the functionality.

How to create a Database in PostgreSQL?

If you have followed the previous steps correctly your environment would be up and running making you eligible to proceed to the next phase of learning PostgreSQL. This sub-section will teach you to create your first database in your system.

Step 1 –

We will create our first database using psql. In the  SQL shell write the following command, which will create a database named Intellipaat.


Step 2 –

Now you have to check whether your database is created or not. By default, it will show a default database. You have to switch between this default database with your created database.

l - to list
c  - to switch

Step 1 –

Open pgAdmin and choose to Create -> Database… from the menu when you right-click the server name (in this case, PostgreSQL 15 by default).

Step 1

Step 2 –

As shown in the image attached, this will launch the Create-Database dialogue. Here, you can enter a database name and choose an owner (Postgres will be the owner by default). In the Definition, Security, Parameters, Advanced, and SQL tabs, you can also provide other settings. To create this new database, click Save.

Step 2

Step 3 –

A freshly formed database will be listed by pgAdmin under the Databases node in the left pane, as seen below.

Step 3

Step 4 –

The database name can be expanded by clicking on it, as illustrated below.

Step 4

So now you can use a wonderful UI-based pgAdmin tool to build and configure a new database.

Deeper Dig: PostgreSQL Features

Deeper Dig: PostgreSQL Features

Now after all the preliminary knowledge, now let’s raise the curtains on the features that PostgreSQL got, because of which it has outshined its alternatives who are there into the business since its inception. Go through the below-mentioned points to the crux behind.

Advantages of PostgreSQL

Let’s start a sequence of sub-series to do the justice with our heading of this section. Let’s take a deeper dive into the features of PostgreSQL.

Disadvantages of PostgreSQL

Let’s have a look over PostgreSQL’s demerits.

Applications of PostgreSQL

This is the last sub-section of our blog, this will let you know about the real-life application of PostgreSQL making it a real-life hero. Check out the below-mentioned pointers to grasp the final piece of wisdom from this blog.

Check out our blog on the frequently asked questions for SQL Server in the interviews Top 35 SQL Server Interview Questions and Answers.


It is seen that the popularity of PostgreSQL is significantly increasing in the technological domain which at the same time increases its demand and the associated manpower. Even though Postgres is still in the development stage, in this short amount of time it has outperformed its competitors and emerged as a significant new rival. The future of PostgreSQL is very secure. It is worth investing your time and money in learning this technology, as more tech giants are adopting it as their main database framework.
