I have to ask, why do you think this is important? For instance, I invented the BRIN interface in 2014 mostly out of thin air. Commit 7516f5259411 (its first) added a lot of new files, and almost all of them were marked with (c) 1996-2014, and all of them (save one, probably by accident) had a (c) 1996 Regents of UC line in addition. The reason I did that, is that most of those files (or probably all of them) were copying something from elsewhere in the tree. Was it worth my time, figuring out exactly which files didn't have a single line copied from elsewhere so that I could restrict the date? My analysis at the time was that it wasn't. Because, you know what? It is unlikely to be important. There was a big licensing change around year 2000 or 2001 from what was believed to be the original Berkeley license to the license we use today (widely known as the PostgreSQL license). The new license is pretty liberal, to the point that there's no reason to try to establish who owns the copyright for each file. Under the old license it might have been important to determine ownership of individual files. -- Álvaro Herrera Breisgau, Deutschland — https://www.EnterpriseDB.com/ Maybe there's lots of data loss but the records of data loss are also lost.
