I am not a part of the PostgreSQL team. So I can't give you anything that is really official. PostgreSQL is a __community__ database software system. If you want to use PostgreSQL and bundle it in with your own software, you may freely (gratis & libre) do so. The PostgreSQL license, shown here:
https://www.postgresql.org/about/licence/ is very "open". Again, the software is both libre & gratis. Basically all you need to do is include the referenced copyright notification in your distribution of the software. If you modify PostgreSQL, you can distribute the binaries __without__ being required to distribute the source. That is, you can "commercialize" your version. A "side effect" of this is that there is no _official_ support. You can report a bug, deficiency, or improvement, but you are not guaranteed that anything will be done (even though something likely will).
note there are many other PostgreSQL consulting businesses who will provide support contracts for the community edition, see https://www.postgresql.org/support/professional_support/europe/ ... I note several of these are in Spain.
