As you probably know PostgreSQL sources are managed by Git version control system. Which is great, but for me as SVN user it would be much better to get access to the sources using familiar tools, e.g. TortoiseSVN. Mainly because I don’t need write access, read mode only. There is a workaround for such guys.
So in my case I need only trunk with the latest commits. I’ve created an empty folder and made Checkout to the https://github.com/postgres/postgres/trunk URL.
