We performed a comparison between MongoDB and PostgreSQL based on real PeerSpot user reviews.
Find out in this report how the two Open Source Databases solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The most valuable feature is that you can store unstructured data, which is helpful when you don't know what the best structure should be and you cannot use a relational database because of that."
"It is easy to set up."
"MongoDB is scalable and stable. The initial setup is very easy, and deployment and maintenance can be done by one person."
"The most valuable features of MongoDB are we have a lot of documentation and SQL-based applications that run on it."
"Scalability seems good. I've never been even close to finding the limits. I've run a couple of notes of redundancy but I've never had any problems with scalability."
"MongoDB's best features are scalability, document management, and data security."
"The integration capabilities of MongoDB are fine for the solutions that we use in our company."
"We've found the product to be scalable."
"It is easy to install and easy to manage. There is no license on it, so it is free. There is high compatibility with Oracle, and there are many tools for the migration of data from Oracle to Postgre."
"PostgreSQL is very powerful, easy to manage, and has many features."
"It's quite scalable."
"I like that you can move any relational database from Oracle to PostgreSQL. I also like that it's pretty stable."
"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 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."
"We are able to create many different types of jobs and items with this solution making it one of the most valuable features."
"What I like is that it's quite powerful in terms of performance."
"They could improve the UI and the analytics part."
"Simplifying the aggregation framework would be an improvement."
"The stability could be improved."
"The scalability of the solution has room for improvement."
"The on-premises version of the solution is still pretty expensive, especially compared to the cloud version."
"The solution should more easily integrate with custom code."
"The MongoDB documentation can be a little complicated sometimes."
"I feel that most people don't know a lot about MongoDB, so maybe they could add some more documentation and tutorials."
"The database and applications can become very slow."
"I'm not really able to customize it."
"We often find the solution's datetime datatype challenging."
"The pricing could be better."
"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."
"PostgreSQL could improve by adding data warehousing tools."
"There could be a plugin to distribute the data on servers for the product."
"There are several features I would like to improve that aren't working as expected. It's likely that the latest version is doing something that was missed in the previous versions. For example, the output parameters — the stored procedures — is something new in PostgreSQL that Firebird has already had for a long time."
MongoDB is ranked 5th in Open Source Databases with 69 reviews while PostgreSQL is ranked 2nd in Open Source Databases with 120 reviews. MongoDB is rated 8.2, while PostgreSQL is rated 8.6. The top reviewer of MongoDB writes "Lightweight with good flexibility and very fast performance for searching data". On the other hand, the top reviewer of PostgreSQL writes " A scalable and stable database for transactional purposes". MongoDB is most compared with InfluxDB, Couchbase, ScyllaDB, Oracle NoSQL and Cassandra, whereas PostgreSQL is most compared with Firebird SQL, EDB Postgres Advanced Server, MySQL, MariaDB and SQLite.

We monitor all Open Source Databases reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
