As an outstanding representative of open source database, PostgreSQL has always been known as the "living Lei Feng" of the open source world. How on earth did this "living Lei Feng" dedicate himself to illuminate others, and why did he have such a high realm and consciousness? Now let's unravel the mystery of "living Lei Feng" in the open source world.

The PostgreSQL license is a free open source license similar to the BSD or MIT license. Before 1994, part of the copyright belongs to the board of directors of the University of California; from 1996 to 2020, part of the copyright belongs to the PostgreSQL global development team; the global development team members are scattered around the world, which is not controlled by any corporate entity, which makes it a truly open project.

The BSD license encourages code sharing, but respects the copyright of the code author. The BSD license is a commercial integration-friendly license / protocol because it allows users to modify and redistribute code, as well as to use or develop commercial software distribution and sale on BSD code. Many companies consider BSD license / protocol open source products first when choosing open source products, because they can have complete control over these third-party code and can modify or redevelop them if necessary.

After listening to this, the veil of "Live Lei Feng" is no longer a mystery. With its free and flexible licenses / protocols, PostgreSQL database is well known and ranks at the top of the open source database rankings.

The most important thing is that such an excellent database management software PostgreSQL is completely free to use, with technical support from the community.
