What Is Open Source?

The term open source has a very specific meaning when applied to software. It means that the software is supplied with the source code included. It does not necessarily mean that there are no conditions applied to the software’s use. It is still licensed in that you are given permission to use the software in certain ways.

An Open Source license will grant you permission to use the software, modify it, and redistribute it without paying license fees. This means that you may use PostgreSQL in your organization as you see fit.

If you have problems with open-source software, because you have the source code, you
can either fix them yourself or give the code to someone else to try to fix. There are now many commercial companies offering support for open-source products, so that you do not have to feel neglected if you choose to use an open-source product.

There are many different variations on Open Source licenses, some more liberal than others. All of them adhere to the principle of source code availability and allowing redistribution.
