Executive SummaryUpdated on Jul 27, 2025

PostgreSQL and MySQL are both prominent contenders in the open-source database management system category. While PostgreSQL often has an edge due to its advanced functionality and compliance with standards, MySQL attracts users with its speed and ease of deployment.

Features: PostgreSQL is known for comprehensive SQL standard support, robustness, and advanced functionality, ideal for feature-rich applications. It handles complex queries and data integrity well. MySQL excels in speed and reliability for web applications, integrates well with programming languages, and is known for fast transaction handling and web integration.

Room for Improvement: PostgreSQL lacks MySQL's broad compatibility with open-source applications, struggles with read-only queries, and does not support some SQL operations like 'INSERT IGNORE'. It also has challenges in user-friendliness and documentation complexity. MySQL faces limitations in standard SQL compliance, complex features like clustering, and lacks advanced replication features available in premium offerings.

Ease of Deployment and Customer Service: PostgreSQL offers a wide deployment range, including on-premises, cloud, and hybrid environments, supported by a strong community but lacking formal technical support. MySQL provides similar deployment flexibility, enhanced by extensive community and enterprise-level support options from Oracle.

Pricing and ROI: Both PostgreSQL and MySQL are open-source with a low total cost of ownership. PostgreSQL's costs are mainly in training and implementation, with support available through consultancy. MySQL offers a free community version and a commercial enterprise edition with advanced features and support, delivering high ROI due to its functionality and cost-effectiveness.

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.

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

"The solution is a small application and is very easy to deploy."

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

"The most valuable feature is the ease of use."

"The solution is free to use, which is its most valuable aspect."

"MySQL solution is overall stable."

"The installation process for the most scalable solution is remarkably quick, taking only a short amount of time."

"We use it as a data store and from that perspective, we get everything we need."

"SKIP LOCKED is a valuable feature."

More MySQL pros

"The product is quite flexible."

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

"Clustering will be the number 1 feature. It is also open-source so it is free. It can also be clustered, to allow fault tolerance."

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

"It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping."

"The database has excellent performance."

"The solution is quite stable."

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

Cons

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

"I would like to improve the solution’s pricing for licenses."

"Its performance should be better. When we use big data, it is slow in performance. We should be able to use mirroring for improved performance."

"The workbench could be improved. In particular, error messages can be improved, which are horrific and completely unhelpful. I'd like to see improved parsing of errors. When you write SQL and it crashes, it usually is something completely irrelevant and not helpful. I've started to use GPT 3.5 for finding out how to do things. I got to do something a bit different, and that I found to be very useful. If there was some way to tie it into one of the new AI tools, that would probably be a good idea."

"MySQL lacks a feature akin to Oracle's Real Application Clusters, which ensures continuous database availability within the same data center or nearby data centers."

"MySQL could introduce more indexing strategies."

"I would like to see some improvements in the solution’s integration aspects."

"There are some issues with compatibility with Java environments that need to be improved. When Oracle bought this solution there were some driver changes that caused some issues with operations."

More MySQL cons

"PostgreSQL could improve by being more user-friendly. In SQL Server they have a studio where you can easily do management but not in this solution."

"It would be good to have machine learning functionality in this solution, similar to Microsoft SQL Server and other solutions. Machine learning capability for a basic level or a common user would be useful. It can also have good reporting capabilities."

"The search option is not very good."

"Sometimes, the views create problems. If you don't have the view, sometimes what happens is you need to have the drivers properly set up for PostgreSQL."

"The interface climate could be better."

"I'd like to see better memory management. I think that that's one of the few areas that Postgres does not handle as well as MySQL does or did."

"They need to improve the user experience of the management."

"Instead of the installation agent downloading all the packages for the install, it should allow the user to download the packages separately on their own to do the install."

Pricing and Cost Advice

"The price of the solution is good because we have a good partner."

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

"We are using the free community edition of MySQL."

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

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

"We pay a yearly subscription fee."

"This is an open-source product that can be used free of charge."

"There is a licensing cost because we are going for a proprietary product. There are some other versions for which there is no licensing cost."

More MySQL pricing and cost advice

"The community version of Postgre is basically free."

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

"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."

"We do not pay for licensing."

"There is an annual license."

"It is an open-source platform."

"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."

What do you like most about PostgreSQL?

It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping.

What is your experience regarding pricing and costs for PostgreSQL?

The tool is free of cost. For now, it's not about making money. But once we perfect it, we can offer it to customers willing to pay for support and other services. Most of my deployments are free.
