Executive SummaryUpdated on Nov 2, 2025

PostgreSQL and MySQL compete in the open-source database management system category. PostgreSQL appears to have the upper hand due to its advanced feature set and strong performance under high workloads.

Features: PostgreSQL offers comprehensive SQL compliance, advanced data types like JSONB, and support for complex queries and operations. It is recognized for superior scalability and extensibility. On the other hand, MySQL focuses on speed and compatibility, making it well-suited for small to medium-sized applications. It supports multi-threaded architecture, LAMP/WAMP integration, and provides excellent performance and stability in various environments.

Room for Improvement: PostgreSQL could benefit from improved documentation and support, as well as enhancements in multi-master replication and partitioning features. MySQL, while easy to use, faces challenges with scalability and lacks advanced analytical capabilities compared to enterprise solutions. It also needs to enhance support for complex data operations.

Ease of Deployment and Customer Service: Both PostgreSQL and MySQL are widely deployed across on-premises and cloud environments. PostgreSQL boasts a strong open-source community that offers extensive support, whereas MySQL, also backed by community forums, is noted for its ease of deployment. However, both lack centralized official support and primarily rely on community or third-party assistance.

Pricing and ROI: Both PostgreSQL and MySQL are open-source, minimizing software costs. PostgreSQL's rich features offer significant ROI for enterprises requiring advanced database functionalities, despite potentially higher personnel costs. MySQL, distributed under GPL, provides rapid ROI with lower overhead, appealing particularly to budget-constrained projects needing simple database solutions.

Offers robust security and availability with impressive replication capabilities

Regarding their documentation and interface, there is room for improvement. Documentation is definitely required when running multiple databases on a cluster system. The load balancer, MySQL LB, which is used to connect to the application, lacks clear documentation. When there are multiple application servers connecting to the MySQL cluster and going through the MySQL load balancer, the documentation is not user-friendly. It's there, but only technical persons with deep knowledge of the MySQL database can implement it. Most of the community users or ISVs who use MySQL don't have many technical persons or DBA experts, so they face some challenges for the high availability of connecting high available databases from high available applications. That documentation should be simplified.

Real-time data capture optimizes database performance but Views create problems

One of the most valuable features is real-time data capture; it optimizes database performance. I think using real-time data capture reduces job running time and the amount of data sent at once with batch loads. Replicating the same data daily isn't optimal, so real-time reception improves application performance and reduces latency.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The speed is very good."

"Like other databases, it has a rich set of functions, such as stored procedures and its own procedural language, which is akin to Oracle SQL. It also has trigger and cursor commands you would expect with a good database language."

"The most valuable feature of MySQL is auto-scaling."

"The most valuable feature is the on-premises data encryption facilities."

"It has a community version. When I have to create a new database, I have no problems with licenses."

"The one interesting thing about this product is that it is open source. It comes from an open source product. MySQL has been positioned as open source, but it also provides support."

"The initial setup was pretty straightforward. I would have worked with our IT team in terms of the initial setup."

"It has a lot of features. The RDBMS, consistency, and multi-user features are valuable."

More MySQL pros

"We often use PostgreSQL for operations monitoring because we are a manufacturing company."

"We managed to reduce the storage space needed to 10% of the original size, without affecting data integrity, and we significantly improved the performance."

"It has completely met our needs. It works, and it is robust. We haven't had any problems with what PostgreSQL does for us and the way it does it. That's why we've been using it for so long. We understand it, and it does the job."

"It's quite scalable."

"The database has excellent performance."

"The built-in code procedural language is the most valuable. It has a built-in layer for code procedures. Its installation is very easy and quick, and it is free. It is also stable, and its performance is also good."

"What I like is that it's quite powerful in terms of performance."

"The solution is open-source and free to use."

Cons

"Sometimes, not because the version is not the latest version, there are some issues with it. Sometimes there's an issue with the server which creates issues with it."

"The performance issues in the product can be considered as an area where improvements are required."

"Since we upgraded from 8.0.12 to 8.0.22, it has had some slowness-related issues. Some of the queries that were fast previously are quite slow now. I did some research, and I found many people complaining about it."

"MySQL's performance needs to be improved for enterprise-level applications compared to Oracle and Postgres."

"It would be helpful if there were a graphical user interface to administer, configure, and tune it."

"The solution could have better integration and security features."

"Scalability could be improved."

"The solution could improve the monitoring. At the present time, you need to use third-party monitoring solutions."

More MySQL cons

"The interface climate could be better."

"There could be a plugin to distribute the data on servers for the product."

"The search option is not very good."

"Sometimes, it becomes slow because of the network. So, there is room for improvement in performance."

"A better graphic user-interface would be nice to see."

"The solution could improve the integration."

"PostgreSQL doesn't have a feature for temporal SQL, which is useful for gathering versions of data. This feature should be included in PostgreSQL. This feature is available in MariaDB, SQL Server, Oracle Database, and DB2."

"The user interface for the clients could be easier to use as they are small businesses. From a technical support perspective, the documentation could be improved."

Pricing and Cost Advice

"We are using the free version of MySQL. We prefer paying for a yearly license."

"We are using the licensed version of MySQL."

"It's free."

"MySQL is cheaper than Microsoft SQL Server."

"There is no licensing fee."

"We are using the free community version of the solution."

"We've never bought a commercial license. We just use the open-source community edition."

"The solution does not come with a licensing fee."

More MySQL pricing and cost advice

"We use the open-source version of PostgreSQL and not the enterprise edition."

"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."

"It is free. In terms of operating costs, it basically needs the same platform on which Oracle runs."

"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."

"The need for our customers to pay for licences is contingent on their projects and budgets."

"It could be much cheaper. If you would like to build an application on Amazon today, PostgreSQL is the standard database with Redshift. If you want other databases, you can add them, but PostgreSQL is the basis of everything. It's a question of money, that's it."

"This solution can offer a cheaper choice for customers since it is open-source."

"The solution requires a license."
