I have Mavericks OS X Server installed on a 2012 Mac Mini Server and am wondering if I can use the PostgreSQL database supplied with the Server App for other uses? I need a database for an personal project I'm working on and would like to use the installed version rather than having to install a separate version. However, I have done some research and the general advice is to leave the Server version alone (because of CalDav, etc) and install PostgreSQL separately. If I have to install separately, should I use the command line and install it myself (which would be good for learning), or would it be better to use an installer package that sets everything up? Thanks in advance.
