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 ?

Best regards,

The licence for all software available on postgresql.org is shown here

https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.postgresql.org%2Fabout%2Flicence%2F&amp;data=04%7C01%7C%7Ce0c997c9e991479cadf708d8e96e15c6%7C1b16ab3eb8f64fe39f3e2db7fe549f6a%7C0%7C1%7C637516006314187203%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&amp;sdata=QL85rotciGB22m6ZOFWusHLh63pn0eXh6c%2FISLmIpfk%3D&amp;reserved=0

The wider PostgreSQL ecosystem consists of many optional extensions and tools, both open and closed source, each of which has different licences. There is no single central place or authority that lists or controls those components and their respective licences. Some are listed here: https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.postgresql.org%2Fdownload%2Fproduct-categories%2F&amp;data=04%7C01%7C%7Ce0c997c9e991479cadf708d8e96e15c6%7C1b16ab3eb8f64fe39f3e2db7fe549f6a%7C0%7C1%7C637516006314197196%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&amp;sdata=Uzh1jvV%2BxHsfufp0qynDPEWuvkzJpD%2FcQqoTVp0eLcw%3D&amp;reserved=0
