I just got a new Mac with Lion installed on it. I then installed Xcode (4.1 through the App Store). Next, I installed Homebrew and I was about to do
brew install postgresql like I had done on Snow Leopard, but I'm reading online that PostgreSQL is already included in Lion.
Can someone confirm if this is true? And if it is included, can I use it for my PostgreSQL server for development (Rails) or is the included PostgreSQL used for the operating system only?
