Firebird, MySQL, and PostgreSQL are probably the most famous representatives of DBMS. Naturally, these projects often are compared with each other - by functionality, usability, etc. We have decided to perform our own code quality comparison of these projects.

The article gives a review of bugs, detected using PVS-Studio static code analyzer. A 'direct' approach of comparing by the number of warnings in this case is badly applicable, so you have to find other ways to compare. For example, you can analyze projects for potential vulnerabilities, as well as to see which of the most interesting errors will be found. By undertaking such a review, you can estimate, which code is better, and find out who will emerge victorious from this battle.

In fact, it's been two days already, but no one has yet written an article on Habr, so I will have to eliminate this omission, which I do with pleasure.
So, what's new in this version of PostgreSQL?
First, the versioning itself has changed. Prior to the "dozens", we observed a lot of minor versions of 9.x that came out about once a year and at the same time introduced serious, far from minor changes. Therefore, since version 10, it has been decided to number 10, 11, 12, etc. By the way, MySQL seems to have gone the same way, jumped from 5.7 to 8.0
Okay, it's all trivia, let's move on to the essence of the question
