Executive SummaryUpdated on Apr 20, 2025

PostgreSQL and MariaDB are leading contenders in the open-source database category, enhancing database management with their unique strengths and features. PostgreSQL appears to have the upper hand due to its advanced features which cater to complex corporate needs, although MariaDB holds a niche for users transitioning from MySQL with its simplicity and performance.

Features: PostgreSQL is recognized for its advanced SQL standards support, scalability, and concurrency which make it ideal for complex corporate environments. Its open-source nature and diverse extensions boost adaptability. MariaDB, known for its simplicity and efficiency, may not have the feature depth of PostgreSQL but excels particularly in aiding MySQL users switching to open-source.

Room for Improvement: PostgreSQL could improve performance on read-only queries and support for certain SQL functions. Additionally, its setup complexity and limited replication features could be enhanced. MariaDB might benefit from improved scalability and robustness for large-scale environments, especially with extensive clustering and replication needs.

Ease of Deployment and Customer Service: PostgreSQL supports a range of deployments including cloud solutions but often requires technical expertise. While community support is strong, centralized tech support is lacking without third-party options. MariaDB offers seamless deployment in similar environments and eases transitions for MySQL users. While it enjoys community-driven support, paid services are available for quick issue resolution.

Pricing and ROI: Both PostgreSQL and MariaDB offer cost-effective solutions being open-source with no licensing fees. PostgreSQL’s rich features may incur higher implementation costs due to the expertise required, whereas MariaDB is more economical in setup and operation thanks to its user-friendly interface and compatibility with existing MySQL installations.

Easy to deploy, cost-effective, and integrates seamlessly with other products

We had planned for an RDBMS version and not NoSQL. We use MariaDB Galera Cluster. It's a good product. It is cheap, scalable, performs well, and is efficient. We use GCP’s BigQuery for machine learning. We must follow the best practices of the tool. We missed some best practices like the storage engine and InnoDB. It was very difficult to identify why we were having performance issues. Then, we realized that some of our tables were still on MyISAM, the default storage engine. When we switched it back to the InnoDB, it was very smooth. InnoDB is the recommended one. We must follow the best practices given in the documentation during the initial setup. Overall, I rate the product a nine out of ten.

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 most valuable feature of the solution is a relational database, which is fairly reliable...It is a stable solution."

"It's a very easy product to set up."

"It's open source."

"It's easy to set up."

"The integration with other products is seamless."

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

"The most valuable features of the solution stem from the fact that it is a cloud-based tool, so it is pretty fast."

"MariaDB performs well as the backend database for our cloud-based telephony solution."

More MariaDB pros

"The solution is scalable, it is very good."

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

"PostgreSQL makes it very adaptable to several descriptions of a record. Instead of having several tables or several relations for one entity, I can adapt this entity. It can be a multiform entity. For example, here in Mexico, a company and a person can be sold to us as a physical entity or a physical person."

"It is very useful for both structured and unstructured data. You can store unstructured and structured data in PostgreSQL. It is easy to use. You can easily manage things through PostgreSQL Admin. It is cost-effective. Its on-premise version is free. It is agnostic of on-premise or cloud. You can install it on the cloud or on-premises. It is available with all clouds, and you can also install it on desktop or Windows Servers."

"The database has excellent performance."

"The product's deployment is easy."

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

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

Cons

"MariaDB can improve by adding more features. There are a lot of features, which are available in Oracle, and which are not available in MariaDB. We hope they will introduce the features soon."

"MariaDB's GUI is an area with certain shortcomings where improvements are required."

"Lacks time series data and additional driving support would be helpful."

"One feedback I can quickly provide is the need for a robust IDE for MongoDB. The existing PHP admin console doesn't meet the client's requirements effectively."

"It would be helpful if I could specify multiple drives for the database storage."

"There is not much support available."

"I’m not sure if it can scale."

"The ability to create stored procedures in MariaDB is an area where the tool lacks a bit."

More MariaDB cons

"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."

"They need to have a better graphical interface. There is a tool called pgAdmin 4 that they use, which is free. It is written in Java, and it is slow. They need to have a better product that is similar to Toad for Oracle, but, of course, it is hard to get something that's really great and free. Other than that, it is great."

"The user interface could be a bit better."

"The solution could improve the integration."

"I'm not really able to customize it."

"The interface could be much better."

"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 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

"The price could be less expensive."

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

"I used the open-source version, which is available free of charge."

"We pay for a yearly license."

"The cost is quite good. You can have the open source, free version, which has adequate capacity."

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

"MariaDB is an open-source software, meaning I don't need to pay for the product."

"It's an open-source solution."

More MariaDB pricing and cost advice

"The community version of Postgre is basically free."

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

"There is an annual license."

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

"The solution requires a license."

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

"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."

Overview

MariaDB is an open source relational database created by the original founders of MySQL. It is considered one of the most popular and trusted database servers throughout the world. MariaDB is a valued component found in most cloud offerings and is the default in many Linux tools. It is also widely used by Wikipedia, WordPress, and Google, among other well-known sites. Maria DB easily melds data into concise information from a vast array of applications, such as banking, online shopping, websites, and more.

MariaDB was originally created to improve MySQL performance. It is the most widely chosen database server due to the solution being super fast, robust, user-friendly, and easily scalable. MariaDB also offers a substantial ecosystem of plugins, storage engines, and numerous other valuable tools that make it very attractive for a significant offering of use cases.

The solution’s newest functionalities include compatibility with Oracle Database and Temporal Data Tables, and advanced clustering with Galera Cluster 4, which make it easier for users to research data history from any point in the past. Additionally, the most recent versions include JSON and GIS features. MariaDB is committed to staying an open source solution.

MariaDB Features

More storage: MariaDB works with more storage engines than MySQL and most other database servers available. Some storage options include, but are not limited to ARCHIVE, MERGE, CSV, MEMORY, BLACKHOLE, MyISAM, ColumnStore, MyRocks, and Cassandra.
Super fast: MariaDB offers faster authentication checks. The FlushSSL permits SSL certificates to be reloaded without a server restart, resulting in huge time savings.
Improved testing: MariaDB offers an extending testing suite that runs faster and can test more than ever before. Bugs can be easily fixed and invalid tests removed.
Genuinely open source: Every code in MariaDB is GPL, LGPL, or BSD. Client libraries [for Windows (ODBC), Java (JDBC), or C] allow linking to closed source software. All fixed bug cases and development plans are completely public. MariaDB is a community-developed solution representing the true spirit of open source products.

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.”
