Executive SummaryUpdated on Apr 20, 2025

PostgreSQL and MySQL are widely used open-source relational database management systems that compete in the database market. PostgreSQL seems to have the upper hand in terms of advanced functionalities and SQL compliance, while MySQL is noted for its speed and performance, particularly in web applications.

Features: PostgreSQL is known for following SQL standards closely and offers advanced features such as full-text search, GIS capabilities, and extensive support for various programming languages. It excels in scalability and robustness for handling large datasets. MySQL, on the other hand, is celebrated for its speed in web applications and provides flexibility with multiple storage engines, making it a favored choice for small to medium applications.

Room for Improvement: PostgreSQL could enhance its handling of certain SQL operations, such as 'INSERT IGNORE' and add support for unsigned integer data types. It has a reputation for a steeper learning curve. MySQL lacks some features like robust replication and transaction handling, and it faces performance issues with intensive InnoDB use compared to MyISAM, which are areas under development.

Ease of Deployment and Customer Service: Both PostgreSQL and MySQL are versatile in deployment, supporting various environments with increased popularity in cloud settings. PostgreSQL offers community-based support, though it can lack formal customer service. MySQL also benefits from a large community, but additional support might be necessary for enterprise setups. Both rely on external resources for technical support.

Pricing and ROI: PostgreSQL is completely open-source, providing a high ROI due to the absence of licensing fees, appealing to cost-conscious organizations. Costs may arise in training and support. MySQL is also open-source for base deployment, but enterprise features might incur additional expenses. Both solutions present excellent ROI, making them suitable for startups and businesses looking to avoid proprietary software costs.

Native encryption ensures secure data management with a simple deployment

The most valuable feature is the on-premises data encryption facilities. By default, we can provide encryption, and this feature in MySQL is why we prefer it over other databases. The native encryption in MySQL encourages us to use this database model more frequently compared to Oracle and other databases. With Oracle, we have to buy another solution for encryption and masking, but MySQL supports native encryption, which enhances our return on investment. It perfectly supports our ROI, and we have no issues with its functionality.

Offers simplicity and is cheaply priced

I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.

Quotes from Members

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

Pros

"I use MySQL for employee service in an OLTP database."

"It is easy to use."

"MySQL is a popular database platform for businesses because it is extremely easy to use."

"It is a very stable solution. I deployed the product six years ago, and it still works fine."

"The solution is easy to use."

"The solution is very simple. It's easy to use. That's the most important feature."

"The solution helps us perform with our databases and extract data."

"One of the most valuable features is MySQL's ability to run our email system. We use a system called Colab."

More MySQL pros

"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."

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

"Postgres has some functions called JSONB aggregators or other aggregators, which are quite useful."

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

"PostgreSQL is stable. It's available, stable, and reliable."

"It is very scalable and comes with a bonus: no licensing issues as you scale with your databases."

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

"The main value is that it is open source, which means it is free. Our organization has the initiative to go to open source to cut down on cost. Oracle costs us $6 million a year right now, which is killing us, and Postgres costs nothing. So, there is a big push to go to Postgres."

Cons

"At times, the autoscaling does not happen when there is a surge in load."

"They should come up with a better solution than the NDB cluster for better scaling. If they could come up with a better solution for write scaling, apart from the NDB cluster, which is supported by all open source communities, that would be great. Although the NDB cluster, I believe, is an open-source tool, it's not widely supported as a solution."

"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."

"It is not as powerful as SQL Server. It can be more powerful. It is not scalable and has certain limitations, which is not the case with SQL Server."

"It could be a little bit simpler to use."

"I am looking for the Temporal SQL feature, which basically means that there is complete history for each table. This feature is currently available in MariaDB. PostgreSQL has something called a foreign-data wrapper, which is another way to access external data from inside. MySQL could have a similar feature."

"The integration with other systems can be improved as can the integration between other databases."

"MySQL could be improved by adding more automation."

More MySQL cons

"It could be more secure."

"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."

"When you get a large number of records in a database and start doing various queries, it can adversely impact the performance of the live running systems. That's an area we continue to look at and mean to improve, but it is not only because of PostgreSQL. It is also because of the way the schemas are put together, and certain events are triggered. So, it is because of both parties."

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

"Integration with other platforms could be improved."

"As PostgreSQL is an open-source product, you do have to do a bit more configuration and management yourself."

"PostgreSQL could improve by providing a geographical solution for tracking trucks and people in the field. They might already have features similar to this and I have not found them. I haven't done research about this topic."

"The search option is not very good."

Pricing and Cost Advice

"My company uses MySQL's corporate licenses."

"Can range from free to quite expensive, depending on the environments and requirements, so better to really set goals ahead of setting it up."

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

"It's an open-source database management system that can be used free of charge."

"It's free."

"I use a free version at present."

"MySQL is very cheap. It could be free. It also has a yearly licensing option."

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

More MySQL pricing and cost advice

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

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

"The community version of Postgre is basically free."

"It is free. There is no license on it."

"It is free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."

"The licensing model is good."

"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."

"We are using the free version of PostgreSQL."
