PostgreSQL vs MySQL: A Quick Guide

Database comparison is vital to decide which one is feasible and suitable for our project. 

PostgreSQL and MySQL are well-known frequently used open-source database systems. Both have their advantages and therefore we need to compare them and decide which is better for our requirements.

Before comparing, let us briefly discuss these database systems.

What is PostgreSQL?

PostgreSQL is a powerful, open-source object-relational database management system(ORDBMS) written in C language. The PostgreSQL project started in 1986 under the direction of Professor Michael Stonebreaker at the University of California, Berkeley.

It is not surprising that many individuals and organizations now favour PostgreSQL as their go-to open-source relational database because of its established architecture, reliability, data security, a wide range of features, and flexibility.

Why PostgreSQL?

  • PostgreSQL is quite extendable. For example, you can create custom functions, specify your data types, and write code in several programming languages without having to recompile your database.

  • It is highly concurrent and ACID-compliant and provides functions, stored procedures, and triggers.

  • To maintain data consistency, Postgres operates a multi-version concurrency control mechanism (MVCC).

Advantages and Disadvantages

What Is MySQL?

A prominent open-source relational database management system (RDMS), is developed, distributed, and supported by Oracle Corporation.

MySQL is used by a lot of major and small businesses. It works with C, C++, and Java to support a wide range of operating systems, including Windows, Linux, MacOS, and others.

It is a user-friendly, fast, and scalable database management system.

Why MySQL?

  •  It improves and extends the flexibility of database administration.

  • Client/server and embedded systems are compatible with MySQL Server.

  •  It is extremely secure and works with all the main operating systems.

Let's compare these two most widely used database systems, based on a variety of various application requirements.

PostgreSQL vs MySQL: Which Database Should You Choose?

There will be numerous considerations while selecting a database system. It must be determined by the expected workload on the database and how scalable the database and the data storage are. Similarly, pricing, features, and add-ons also play a significant role when selecting.


In this article, we have compared PostgreSQL and MySQL features and the specialized differences too.

Each has its advantages and disadvantages. Considering the comparison and explanation, we can select the appropriate database for our project.
