We don't have the complete version history of postgres, so that's not easy to know. There definitely are still lines from Postgres95 that haven't been changed since the initial import into our repository.

Somewhere there's a CVS repository with some history from before the import into the current repository, but unfortunately there's a few years missing between that repository and the initial import. I've not done the work to analyze whether any lines from that historical repo still survive.
