When we did the migration to git, we decided to leave the old
postgresql git repository around "for a while", for people who had
clones around it. This is the repository that was live updated from
cvs while we were using cvs, and does *not* correspond to the current
git repository when it comes to hashes and other details. It's
available at http://git.postgresql.org/gitweb?p=postgresql-old.git;a=summary
I think it's time to drop this repository now. Anybody who had active
clones on it should've moved to the new repository by now, I think.
