Why Should You Learn PostgreSQL?

We're big fans of PostgreSQL. It’s a great solution that will work for most relational database use cases. In addition, Postgres (PostgreSQL’s nickname) is free and has a large and active community, thanks to which it is constantly growing and getting new extensions and add-ons.

Statistics show that PostgreSQL is one of the three most popular databases in the world. Many rankings, including the Stack Overflow Survey, put it in 2nd place, ahead of such giants as MS SQL Server, Oracle, and SQLite. If you want to know more, take a look at The Most Popular Databases of 2020.

The fact that this is an open-source solution does not mean that it is not used by major companies. Instagram, Skype, Reddit, and even NASA use PostgreSQL, which is a pretty strong recommendation.

All in all, learning PostgreSQL is a great idea. It will give you not only a way to use a great tool but also a skill sought by employers around the world.
