Open source licenses
Dear PostgreSQL Team, We are a software editor that historically use PostgreSQL for one of our product. We currently use the version 9.6 since many years and now we would like to update to the last version 13.2. However, before that, we would like to check some points regarding the embedded components and their licenses. First, we install PostgreSQL with our installer using the Zip archive of binaries (for Windows) provided by EDB (available from your website). It seems that the EDB Zip archive embed PgAdmin and StackBuilder in addition to the PostgreSQL server. Do you know if some others modules are added by EDB ? Then, it appears that the PostgreSQL server links some open source components that are not under the PostgreSQL license( ex: openssl, libcharset, ...). Could you please provide a list of the components included in the PostgreSQL server, with the OpenSource license type for each component ? Or even, if possible, with the license file for each component ?

RE: Open source licenses
My concern is, I guess, the same for all the software editor using opensource components. It is to make an inventory of all the used opensource licenses from all the used components, to check and respect the terms of use, to preserve copyrights and intellectual property. Companies providing opensource components or libraries now often publish a list of the modules and their licences because most of the time it is a prerequisite for the adoption in many companies. For example, Qt Company publishes this page: https://doc.qt.io/qt-5/licenses-used-in-qt.html. However, when I get PostgreSql binaries for Windows (Zip archive linked to https://www.enterprisedb.com/download-postgresql-binaries), I can see in installation-notes.html : -> "The software bundled together in this package is released under a number of different Open Source licences. By using any component of this installation package, you agree to abide by the terms and conditions of it's licence." This is unclear and even if I found some license files, or header files with copyrights, I cannot know certainly the list of installed components and their licenses. And finally, whatever if I use a component, as soon as I install it, I distribute it and thus I have to know the conditions. Could the PostgreSQL Global Development Group consider to provide these information ? Is there a team or a group in charge of this ? Is there a direct email address to ask this kind of request ? Best regards, Nicolas DAVID
RE: Open source licenses
Yes sure. I also did it ... without answer. But my initial question concerned only the open source components linked to the PostgreSQL server that are not under the PostgreSQL license( ex: openssl, libcharset, ...). Regarding the other modules added by EDB, I will ask again to EDB.

I think your request is reasonable, but you'll have to ask the packager.

RE: Open source licenses
Dear All, As I solution, I wanted to start to build Postgres from source by myself, in order to better managed what it is finally included. So I wanted to compile on Windows with Visual Studio. However, in the page https://www.postgresql.org/docs/current/install-windows.html, I can see: " It is recommended that most users download the binary distribution for Windows, available as a graphical installer package from the PostgreSQL website. Building from source is only intended for people developing PostgreSQL or extensions. " Why this recommendation ? Is there any "risk" by building from source ?

That depends on how PostgreSQL was configured. It may be a bit cumbersome, but you could go through all the shared libraries (DLLs) in the "bin" directory that do not belong to PostgreSQL. The licenses for software like OpenSSL should be easy to find.
