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.

Robust relational data foundation has supported rapid growth and improved user data management

MySQL can be improved in several ways. It has connectivity errors and administration troubles that sometimes occur, though not consistently. MySQL has slow queries; sometimes when I run a query, it scans the whole table, and if the data is very large, it takes too much time to retrieve the data. There can be resource bottlenecks with RAM and CPU usage being a little lower than ideal. Monitoring system metrics is crucial because we need to identify and address these types of issues. Schema designing is another area for improvement, as a poorly designed schema can lead to data redundancy in the future. If I haven't initially planned for a 20 lakh user database and am only working with a 1,000 user case, it will be very problematic because in the future, it will affect the whole table structure, and we will need to change everything. Thorough thinking is necessary before even creating the table. MySQL documentation could be better. Sometimes when I need to find something related to MySQL, the documentation is not very comprehensive. If I have a problem with it, I have to go to Stack Overflow or something similar to get the full detail. Additionally, sometimes when we are connecting to local MySQL, it says we cannot connect to SQL, and I don't know the reason. The error messages are not very helpful, so we have to investigate those cases manually. There are multiple instances of this occurring. Documentation can be better overall. The integration capabilities could be improved slightly. Whatever I have used is working fine for me currently, but it could be a little better. The UI of MySQL Workbench, which I use, is not appealing to me, so it could be improved. MySQL overall is very good, and the foundation is very strong. We can develop features around it and different types of things inside it, which will make it better in the future.

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.

"When comparing MySQL to other solutions it is easier to use and boots up faster. Additionally, when you want to query a lot of data, MySQL is better in performance."

"One of the best features is this solution is easy to use."

"It is very easy to install and has all basic database features."

"It has a remote access feature to manage the database from a remote location. This enables in-work collaboration."

"MySQL is open-source. There are a lot of open-source communities trying to come up with their own patches, and to come up with their own features, which help MySQL develop faster than traditional databases like Oracle, which is closed source."

"As an RDBMS, MySQL provides us great capability, and for a product growing to large scale like ours, where we currently have around 10 lakh users but will grow to 20, 30, 40 million or more, having a strong database foundation is essential and MySQL provides that."

"What I've been most pleased with is the cost point, performance, and ease of use."

"I like MySQL's feature that helps to automate things."

More MySQL pros

"We use the solution to store tables. It is stable and performs well."

"Scalable, stable, and easy to manage database system, with a straightforward installation."

"The community support and the open-source community for it are good."

"PostgreSQL is very easy to use. I have experience in Oracle SQL and PostgreSQL uses the same syntax which makes it is easy for me to develop."

Cons

"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."

"When working with a cluster wide, I have to use the MySQL cluster version."

"On the database side, it should be really lightweight, and the data structure should be like MongoDB."

"While utilizing a comparable algorithm, is noted to be sensitive, especially when configuring the inner device."

"Oracle should start putting in some of the enterprise features in the standard feature. There are some key features that should be part of the standard."

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

"MySQL has slow queries; sometimes when I run a query, it scans the whole table, and if the data is very large, it takes too much time to retrieve the data."

"Improvements are required in character set support, scalability, and big data sets."

More MySQL cons

"Integration with other platforms could be improved."

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

"The pricing is not much expensive, it's cheap."

"It has a community version."

"MySQL is a cheap solution."

"It's cheaper than other solutions."

"MySQL Enterprise Support is not cheap, though might still be cheaper than Oracle or SQL Server. They may not have local support depending on where you’re based, but there are many smaller agencies out there that will readily provide support. You’ll need to spend some time looking around."

"MySQL is a free and open-source solution."

"It is open source. We prefer it for POCs because it saves the license cost."

More MySQL pricing and cost advice

"It is also open-source so it is free."

"The licensing model is good."

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

"It is open source. There is no licensing."

"The tool is cheaply priced compared to other RDBMS providers in the market."

"We do not pay for licensing."

"It is open-source. If you use it on-premise, it is free. It also has enterprise or commercial versions. If you go for the cloud version, there will be a cost, but it is lower than Oracle or Microsoft."

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