PostgreSQL vs MySQL

PostgreSQL vs MySQL

With the rise of the internet, the amount of information flooding digital spaces is enormous. Data is an abundant resource available today that must be leveraged to make the most of any business. By collecting and analyzing all the available data, companies can understand customer trends and work on being more productive and successful. Finding patterns in the data available to them can help businesses identify better opportunities as well.

We can't talk about data without the need for databases. Databases are usually part of the backend of any website or application that collects and stores data. PostgreSQL and MySQL are two of the most popular open-source databases in use today. Both of these are relational databases. This means that they arrange information in tables, which can be connected to each other through keys.

These two databases are becoming more similar to each as each update is released. Both of them are known for the vast community support available to them as well. Essentially, MySQL is a more straightforward database that is easier to set up and operate. At the same time, PostgreSQL is more feature-rich and can be used for more complicated and analytical tasks. The two of them have many similarities and several differences as well.

Let's take a deeper look at both of these databases.

General overview of PostgreSQL vs MySQL

MySQL is a purely relational database, but PostgreSQL is an object-relational database or an ORDBMS with capabilities like table inheritance as well as function overloading. SQL, or the Structured query language, is the common language for interacting with relational database management systems in both PostgreSQL and MySQL.

Since SQL has a straightforward structure and lesser lines of source code, most nontechnical personnel can pick it up fast. SQL eliminates the requirement for analysts to understand the location of the order table on a disc, how to conduct a search to locate a particular order, or how to link the order or customer tables. The query is built by the database, which also determines the proper data points.

Both databases support JSON - JavaScript Object Notation. The PostgreSQL database also offers the binary form of JSON that removes duplicate keys and excessive whitespace - JSONB. In addition to more conventional assistance channels, both databases provide strong community support as well.

MySQL: General Overview

MySQL was released on 23rd May 1995. Over 50% of programmers use MySQL as of 2021. With this, MySQL will be the most widely used database management system on the planet. MySQL is one of the quick, dependable, all-purpose relational database management systems. Despite lacking PostgreSQL's comprehensive feature set, it is a great fit for a variety of apps, notably web applications.

MySQL is the preferred option for dynamic web applications, partly because it is a component of the LAMP stack by default. The LAMP stack is an open-source set of online apps that is made up of Linux, Apache HTTP Server, MySQL, and PHP. MySQL is also used by a wide variety of content management solutions, including Joomla and WordPress.

MySQL is open-source and free to use. Oracle maintains it, and there exist premium versions of MySQL with extra services that require the user to pay for it. The premium versions have exclusive plugins, modules, and customer support.

You don't have to worry about any programming doubts that may pop up while you are building a project or learning MySQL. Troubleshooting assistance can be obtained from a committed group of volunteers. The community support available for the database is incredible, as there are developers always ready to help and reply to online queries. As long as you carry out routine maintenance schedules and keep your databases tidy, MySQL users feel that it is a pretty consistent RDBMS.

Multi-version concurrency control or MVCC features are available in MySQL, which also enjoys regular updates that add new functions and strengthen safety. On 6 July 2022, version 8.0.30 of the database was released. This is the latest stable update available for the database. Popular companies like Facebook, Google, GitHub, NASA, and others make use of MySQL features in their back-end.


PostgreSQL: General Overview

PostgreSQL is an open-source relational database with a solid reputation for dependability, versatility, and compliance with open technical standards. The database is also referred to as Postgres. The database was released for the first time in 1997. Several relational and non-relational databases and data formats are supported by PostgreSQL. The database has been referred to as being one of the most developed, stable, and conforming relational databases currently available and is capable of handling challenging queries.

The PostgreSQL database allows several impressive features, like Point-in-time recovery or PITR, which allows for the restoration of databases to a specified time point. Additionally, it provides a Write ahead log or WAL that uses programs like pgBackRest to record any database modifications. The database also enables the creation and storage of unique subroutines using stored procedures. On October 13, 2022, PostgreSQL 15 was released, which is the latest version of the database.

With a strong extension environment, it is adaptable and scalable enough to easily accommodate a range of different use cases, including initiatives such as time-series data types as well as geospatial analysis. PostgreSQL was created as an open-source database system. Therefore it has no license limitations, vendor lock-in concerns, or over-deployment risks.

PostgreSQL may be modified by creating plugins to meet your needs and make the DBMS more efficient. Additionally, PostgreSQL enables you to use custom functionality created in other computer languages, like C/C++, Java, and others.

For business admins in charge of overseeing online transaction processing protocols for commercial operations like e-commerce, customer relationship management systems (CRMs), and accounting ledgers, the PostgreSQL database provides the best option. Some of the notable names who make use of PostgreSQL in their back end include Apple, Etsy, IMDB, Instagram, and more.


The critical differences between Postgres and MySQL

There are several differences between Postgres and MySQL. Some of these are based on how the database was built, while other differences are in their functionality and use cases.

The GNU General Public License has been used to make the source code for the MySQL database accessible to all. At the same time, PostgreSQL is made available under the PostgreSQL license. PostgreSQL is fully ACID compatible, but MySQL is only ACID compliant when coupled with the InnoDB and NDB Cluster Storage processors.

The MySQL database is only weakly consistent with SQL. For instance, check constraints are not supported. PostgreSQL, on the other hand, mainly complies with SQL standards. Many web applications that require a database for simple data transfers utilize MySQL. In complex networks where read-and-write database performance is crucial, Postgres is frequently employed.

MySQL was written in C/C++, while Postgres was written in C. MySQL does not support cascade, while Postgres does. MySQL uses Workbench GUI as its user interface, while Postgres uses PgAdmin. MySQL supports SQL syntaxes and stored procedures, while PostgreSQL supports advanced procedures and stored procedures.

The allowed index type for MySQL is the Binary Search Tree, while Postgres supports many such index types, including GIN and Hash. MySQL uses Transport Layer Security (TLS) protocol for security, while Postgres uses the SSL protocol. The MySQL database doesn't support advanced data types, but Postgres allows for advanced data types, including user-defined data types.

MySQL vs PostgreSQL

Why do developers choose one over the other?

Both MySQL and PostgreSQL have features that shine in certain use cases. For example, if you are building a simple database, you might want to go for MySQL. At the same time, if you are building an application that requires more features and analytical capabilities, you might want to choose PostgreSQL.

DBMS developers choose between the databases based on the use case they are working on and what functionality they need for that particular project.

Why do developers choose MySQL?

You can choose from a variety of storage processors when using MySQL. You now have the freedom to combine information from several tables as well. MySQL maintains its minimal weight to prioritize performance and dependability by leaving out specific SQL features. Particularly concerning read-only, highly concurrent tasks, MySQL's database performance is noticeable. Because of this, it's a great option for several business analytics tasks. PostgreSQL might be a better option, though, if you want to execute a lot of intricate queries while dealing with high traffic.

By modifying parameters like sort buffer size, read buffer size, max allowed packet, etc., MySQL provides a variety of choices for modifying and optimizing your MySQL server. Finding database administrators with MySQL expertise is simple as well, thanks to MySQL's widespread use.

Additionally, its users claim that it's simpler to configure and requires less fine-tuning than other DBMS systems. In addition, several front-ends, such as Adminer, HeidiSQL, and more, give MySQL a graphical user interface, making it more user-friendly. MySQL is prepared for the cloud as well, and many cloud computing services include MySQL capabilities, where they will set up and manage MySQL databases for a charge.

Why do developers choose PostgreSQL?

PostgreSQL is slightly more complicated than MySQL, and you might need a little bit more technical information to use it. Since PostgreSQL is an object-relational database, it bridges the gap between relational programming and object-oriented coding. This enables the definition of objects as well as table inheritance, leading to the creation of more intricate database systems.

When working with information that doesn't fit neatly into a rigidly relational model, an object-relational database is great. PostgreSQL is a great option when you have to carry out challenging read-write processes while using information that needs to be validated. However, while dealing with read-only activities, the ORDBMS could be slower than usual. A prominent option for NoSQL capabilities is PostgreSQL. JSON, hstore, and XML are just a few of the broad diversity of data types that it natively offers. You can create unique data types and your own functions as well.

Databases can be any size with PostgreSQL. Another main factor that influences a company's decision to choose PostgreSQL is multi-version concurrency control - MVCC. Multiple readers and writers can connect with and control the PostgreSQL database technologies at once, thanks to MVCC. This increases performance by removing the necessity for a read-write lock whenever a person needs to deal with the data. This is accomplished by MVCC using snapshot isolation. Snapshots show the data's condition at a specific time. At the transactional level, PostgreSQL guards against data corruption and maintains the confidentiality of the information.

PostgreSQL vs MySQL: Which is faster?

If we compare PostgreSQL vs MySQL, it is clear that both are among the quickest database management system options. The question of which is faster is, however, not easily answered. Speed tests produce contradicting findings.

Speed largely depends on how you're utilizing the database. For managing large data sets, challenging searches, and read-write operations, PostgreSQL is renowned for being speedier. Similarly, if we are only taking read-only instructions, MySQL runs more quickly.

PostgreSQL vs MySQL: What all computer languages do they allow?

Both MySQL and PostgreSQL support several programming languages. Some of them overlap as well.

MySQL-supported languages

MySQL can work seamlessly and supports the following programming languages:

  • C/C++
  • PHP
  • Java
  • Go
  • Delphi
  • Lisp
  • Erlang
  • Node.js
  • R
  • Perl
  • PHP

PostgreSQL supported languages

PostgreSQL supports a larger number of programming languages. They include the following:

  • Go
  • C/C++
  • Java
  • Delphi
  • Javascript
  • Erlang
  • Lisp
  • R
  • .Net
  • Tcl
  • Python

PostgreSQL vs MySQL: What operating systems do they work with?

Several operating systems are compatible with both MySQL as well as PostgreSQL. MySQL, as we've mentioned above, provides cloud assistance and is easier to use. The operating systems that MySQL can work with are:

  • Windows
  • Linux - Ubuntu, Oracle, Debian, SUSE, Generic, Red Hat Enterprises
  • macOS
  • Oracle Solaris
  • Fedora
  • FreeBSD
  • Open Source Build

Users usually deploy PostgreSQL on Linux systems, but it also supports on-premises setups and cloud-based assistance. The ORDBMS also provides the PostgREST REST API. A solitary web SQL server called PostgREST converts the PostgreSQL system into a RESTful API. The API routes and actions are dictated by the technical limitations and rights in the database. The operating systems that work with PostgreSQL include:

  • Windows
  • macOS
  • BSD - Free and open
  • Solaris
  • Linux - Debian, Red Hat family Linux, Ubuntu Linux, SuSE, OpenSuSE

PostgreSQL vs MySQL: How do they index?

To accelerate SQL commands while working with huge data tables, indexes help relational databases function better. Searches would be laborious and time-consuming for the database management system without indexing a database. When comparing PostgreSQL vs MySQL, various indexing choices are available.

Index types in MySQL involve indexes like INDEX, PRIMARY KEY, FULLTEXT, and UNIQUE that are stored on B-trees. MySQL also has R-tree-based indexes, including those for spatial data. When utilizing FULLTEXT indexes, hash indexes, as well as inverted lists, are used.

How is coding different with PostgreSQL vs MySQL?

We have seen some of the major differences between MySQL as well as PostgreSQL when it comes to programming languages, functionality, and more. But how do they differ when it comes to actual data manipulation? Coding in both MySQL and PostgreSQL has some similarities, but they have many differences as well.

MySQL doesn't care about the case. It is not sensitive to the case of the characters. You don't have to capitalize strings exactly as they exist when doing searches. PostgreSQL takes cases into account. It is sensitive to the case of the characters. So a capitalized string and an uncapitalized string will be two different variables. Strings must be capitalized precisely as they exist for the search to succeed.

It is important to convert character encodings and strings to UTF-8 when using specific variations of MySQL. It is not essential to change characters as well as strings to UTF-8 while using PostgreSQL. Furthermore, PostgreSQL does not support the syntax of UTF-8.

In MySQL, using the IF o IFNULL expressions is acceptable. IF, as well as IFNULL expressions, are invalid in PostgreSQL. Alternatively, you must employ a CASE statement. These are the main differences that you should take into account while coding in MySQL vs PostgreSQL.

No-Code Development

No-code development has made the creation of software applications more accessible to the general public. What was once something that only software engineers could do, is now a process that has a much easier learning curve. Rather than using conventional computer programming, no-code development environments enable both programmers and non-programmers to construct software applications via user interfaces and setup. It is changing the way people approach programming, as coding has become far more accessible today with no code.

Today, you can create an application even with minimal coding skills with the help of no-code platforms like AppMaster. You can create amazing applications that work perfectly with the platform. You don't have to worry about the flights of the source code you create either. The source code of your applications will belong to you. You can quickly create the source code of a mobile application by just dragging and dropping objects and making edits. AppMaster also has a drag-and-drop visual builder. With it, you can manage your mobile applications or build a web admin panel for administrators.

With the database designer, you can easily design a complex enterprise-level database. The database runs on PostgreSQL, using an advanced DBMS, which significantly increases your applications' reliability and fault tolerance. The DBMS has an open license, and you do not have to pay extra for its use.


We have covered the major differences that divide MySQL and PostgreSQL above. Knowing the benefits of both databases and understanding the places where they can do better than the other is important. This can help you choose the right database management system while building your web applications.

You should choose PostgreSQL if you're searching for feature-rich database technologies that can easily handle large databases and complicated searches while enabling you to scale any project to corporate scope. On the other hand, you might give MySQL a try if you're a novice searching for a database that is simpler to maintain and set up yet still dependable, quick, and well-understood. If you still can't decide between the two, consider testing them both out and then making your decision.

Depending on the functionality and complexity of your application, either MySQL or PostgreSQL might be the right choice for you. There are other databases out there, like MongoDB or MariaDB, that also provide similar services. Even with such alternatives, MySQL and PostgreSQL have remained some of the most well-liked databases for DBMS developers.
