Complex performance optimization

54% of reviewers feel negative about PostgreSQL’s performance tuning. Some users say optimizing performance requires significant expertise and regular maintenance, such as managing vacuum processes and tuning configurations. Reviewers indicate that resource consumption can be high, especially in large-scale deployments, and that poor tuning may lead to slow operations. They find documentation and guidance on optimization lacking compared to other platforms, making it challenging to achieve peak performance without deep technical knowledge.

Challenging installation process

One thing that i dislike from PostgreSQL is it's hard to setup and install PostgreSQL at the beginning.

40% of reviewers feel negative about PostgreSQL’s setup experience. Users find the installation and initial configuration process to be more complicated than with other databases, especially for beginners. They say documentation is not always clear, and setting up on different operating systems can be confusing. Some reviewers report issues with default settings, credentials, and enabling necessary drivers. They indicate that the setup process can be time-consuming and sometimes requires troubleshooting, making it less accessible for those new to database management.

Slower operations for some tasks

40% of reviewers feel negative about PostgreSQL’s performance and speed. Some users report that insert, update, and read operations can be slower compared to other database systems, particularly with small databases or under heavy load. Reviewers indicate that the platform may not cache query execution plans efficiently, leading to delays in repeated queries. They also mention that performance issues can arise if the database is not properly configured or normalized, and that simultaneous user access may further impact speed.

Steep learning curve

40% of reviewers feel negative about PostgreSQL’s ease of use. Users think the platform can be difficult to learn, especially for beginners or those coming from other databases. They say the syntax for complex queries and administrative tasks is not always intuitive, and documentation can be hard to navigate. Some reviewers report that initial configuration and troubleshooting are cumbersome, and that the user interface is less friendly compared to competitors. They often turn to community blogs rather than official manuals for help.

Senior Data Engineer

The only problem I faced with Postgres SQL was that API people need column comments, and for a table with huge number of columns like 250-300 fields, it is very hard to update column via SQL query. And there is no provision in Postgres to tag comment to a column with DDL statement.

Senior Software Developer

One of my favorite features is that PostgreSQL can be learned quickly and easily because there are many resources, it has high performance, it can easily handle very large data operations and high instantaneous transaction loads.

I love using PostgreSQL for the following main reasons, firstly databases with a lot of data can be stored, it is possible to have different settings for various databases on a same server and on top that it costs nothing to use PostgreSQL since it is an open source software.

Postgres implements catalog internally, so it stores differently from other RDBMS(s).

PostgresSQL is very famous among the data engineering fraternity due to its high resilience and throughput.

PgAdmin is best tool to manage the DB with intuitive UI.

The query performance was identified and optimized with the use of the performance analysis tools, resulting in effective data retrieval.

Student

The diagram feature isn't as customizable as I would prefer.

I strongly rely on PostgreSQL as a data-driven professional to store, retrieve, and analyze massive volumes of data.

Full stack developer

subqueries and json native compatibility is a game changer

Software

PostgreSQL excels in its strong documentation, large data handling, and exceptional security.

I haven't used database management systems for very long, so navigating PostgreSQL's installation and configuration options proved to be a challenge.

In my experience with PostgreSQL, its adaptability and dependability as a database management system were its strongest points.

The ability to import and export data has also made it simple to move data between platforms.

My least favorite aspect about PostgreSQL was the steep learning curve and complexity involved in setting it up and configuring it.

Challenges with screen navigation, JSON handling, and data comparison can make it less user-friendly

Web Developer

PostgreSQL is a powerful and reliable relational database management system, however, its setup and configuration can be complex, and it may not perform optimally in certain high-speed or large-scale data processing scenarios. Despite this, it offers advanced data management and security features, and it supports data replication and backup/recovery

Prominent and self-proving features,* Supports any OS independent environment* Support for software languages from many different languages* Active use in many relational or non-relational databases,* Supports many data types and types,* Redesignable code structure

I was able to very easily do this with a combination of python for data processing, tableau for visualization and postgre-sql for the database.

CISO

Free for commercial use, Highly expandable, Largely compliant with SQL standard, Flexible full text search,Possible to process complex data types

Security Architecture Discipline leader

I think the popularity of MySQL as an RDBMS is split in two, but PostgreSQL does not have the following MySQL keylogging problem, so it can be said that it is an RDBMS with little custom.

I like PostgreSQL's broad range of features and capabilities as a data specialist.

Senior Consultant

Since it is OLTP and thus row-optimized, Postgres is not suitable for analytical workloads, which are becoming increasingly common with the advent of AI and machine learning applications.

Overall, PostgreSQL is an excellent choice for businesses looking for a powerful and flexible relational database management system, it offers great features that make it a great tool for most of use cases.

we can use Change Data Capture feature to track the changes on data on tables.

Postgres has your back with plugins that can handle it all.

User management is very flexible and the query language support many things that MySQL does not out-of-the-box, more inline with oracle database.

Senior Devops Engineer

One of the feature which i feel is missing in postgres is while we take the dump of database we dont get the user details in the dump.

Lead UI Developer

I started using it because of my university and I was instantly charmed by how user-friendly the software is with its tools.

You can download it for free, and it has a user-friendly interface that simplifies data management and querying.

Sometime when we use bulk mutation queries when updating database, search query latencies will increase.

It also allows scalability, which makes it suitable for handling an increasing amount of data and users.

It is a robust and reliable database system with advanced features for data management and analysis.
