Can Postgres replace Redis as a cache?

In the article on Dizzy.Zone, the challenges of using Redis for data storage in relation to databases such as PostgreSQL are discussed. The author points out that while Redis is known for its speed and performance in caching, it may not be suitable for all use cases. An important point made is that every technology comes with its limitations, which should be considered before deciding on implementation. The article also touches on the costs of maintenance and monitoring of data, which is essential to avoid issues with data integrity. The question arises: do we really need Redis to improve performance, or is it better to optimize our database and utilize its built-in features? Answers to these questions may depend on the specific use case and application architecture, making it vital to carefully consider before making decisions. Additionally, the author emphasizes the significance of testing, which allows for a thorough evaluation of both Redis and PostgreSQL in our project.
