Executive SummaryUpdated on Feb 8, 2026

PostgreSQL and MariaDB compete in the relational database management system category. PostgreSQL appears to have the upper hand due to its extensibility and support for complex queries which are highly valued by users.

Features: PostgreSQL is known for its advanced feature set including support for JSON, NoSQL operations, and robust indexing which enhances performance in large-scale environments. In contrast, MariaDB emphasizes SQL compliance and ease of use. PostgreSQL's superior extensibility and capability to handle complex queries make it the preferred choice for those who need these advanced features.

Room for Improvement: PostgreSQL could benefit from improved GUI tools and enhanced documentation, as well as better scalability and replication features. MariaDB, meanwhile, should enhance its replication capabilities, customization options, and handling of large-scale data.

Ease of Deployment and Customer Service: Both PostgreSQL and MariaDB are popular for both on-premises and cloud deployment due to their open-source nature. PostgreSQL has a strong community offering comprehensive resources and active forums, whereas MariaDB is known for its straightforward implementation. However, neither offers dedicated customer service.

Pricing and ROI: Both PostgreSQL and MariaDB are free and open-source, offering cost-effective solutions without licensing fees. This fosters high ROI, particularly for small to medium-sized businesses looking for powerful yet affordable database management systems.

Has supported web application data needs but requires design adjustments to manage complex queries efficiently

Complex queries in MariaDB where the query needs to parse thousands of lines or data values face some performance issues. For small and medium-size volume, it is pretty good. If it goes beyond certain data and complex queries, we see performance issues. We tried the advanced replication feature between different regions, replicating data specifically residing on MariaDB to two different regions of MariaDB data, and there were some technical snags in terms of slowness and longer processing time. Point-in-time recovery in MariaDB is good for small databases. When data volume increases beyond 5 GB or 10 GB per day or runs into double-digit GBs, we found some performance issues. For data below 10 GB, it works fine. Performance is the primary focus area for MariaDB, particularly during transactions or complex query jobs where slow performance is observed. MariaDB is scalable and easy to scale.

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

"It is an absolutely stable solution."

"The most valuable feature of MariaDB is the replication mode."

"The solution's features have effectively met our operational requirements as a standard SQL database."

"The solution runs very quickly. It's not slow at all."

"The speed and functionality are the most valuable features."

"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."

"The solution is very stable. It was originally built under MySQL. It has a similar level of stability."

"It's easy to set up."

More MariaDB pros

"With the database, you can provide a multi-component at the same service with the same performance, scalability, or all those things."

"It is a pretty comprehensive database system. Its performance is good, and it does what it is supposed to do. It also integrates very well."

"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."

"The product is quite flexible."

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

"It is easy to use."

"It is very simple to manage."

"The solution has many valuable features such as it easy to use and the interface is intuitive."

Cons

"Maria DB has to improve from a management perspective."

"Replication could be better, and it's not so simple. It would be better if they had a replication server. It would make things a lot easier. You need to have that replication server, but not in the same server farm. Then there will be a bit of latency between both because you should have one in one city and another one in a different city. That kind of solution should be more baked into every single database today. Mirroring the database in a live environment where any record written on the production server replicates instantly across the fiber on the other server wasn't easy. Many people don't even bother with that, and they just run one server."

"I am editing."

"The only potential area for improvement could be the pricing model, which might benefit from being more flexible or a bit cheaper."

"MariaDB doesn't handle long or complex SQL queries quite as well as Oracle Database."

"There is not much support available."

"It doesn't have the same level of maturity metrics as Postgres."

"Sometimes, complex queries that were supported in Oracle are not available in MariaDB."

More MariaDB cons

"The interface climate could be better."

"The pricing could be better."

"I had some issues when I integrated with the Jupyter Notebook."

"If it was free to use, it would be the perfect solution."

"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 could be a bit better."

"We have to set up event API, which takes a lot of events from the user."

"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."

Pricing and Cost Advice

"We pay for a yearly license."

"The price could be less expensive."

"The licensing cost is approximately $4000.00 per year and the licensing is based on the software and the number of posts that you make."

"MariaDB is a free-to-use solution."

"This is an open source solution with no licensing fees."

"There is a monthly subscription to use MariaDB."

"The tool is open-source."

"It is an open-source solution."

More MariaDB pricing and cost advice

"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."

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

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

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

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

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

"There is an annual license."

"We do not pay for licensing."

Reviews from Real Users

Faustine C., Engineering Supervisor- Corporate Data Solutions and Services at TZ Telecoms Corporation, shares, “The software provides a lot of information on what is happening inside the database. For most performance parameters it is easy to know if something is not right in the configuration or optimization which helps engineers take remedial fine-tuning measures. For example, if the database is underperforming it is easy to know which performance parameter can be adjusted to handle the workload. It is difficult to troubleshoot database issues if many performance parameters can not be monitored or debugged which is the case with some database management systems. It provides great monitoring of data storage, processing, and performance stability which is really important for real-time data storage and processing. It's a user-friendly product.”

A PeerSpot user who is a Senior Engineer at a tech services company relates, “ The solution's high availability is its most valuable aspect. We have found the product to be stable and the initial setup is pretty simple. I'd rate the solution at a ten out of ten. I'm very happy with it overall. I would recommend the solution to others. It's easy to find details about the product online and to learn about it.”
