Setting up Postgresql on

This is rather quick and easy to do. On MacOS, make sure you have Homebrew installed and then follow those instructions.

For me, it took a few additional steps because I was installing it on a new mac mini (in the home office). I had not made sure everything was up-to-date before starting so I had to walk away for a little bit to let it all happen. No biggie.

rodney@rodneys-mini ~ % brew install postgis
Error: The following formulae
  [#<Dependency: "python" []>, #<Options: []>] and [#<Dependency: "gcc" []>, #<Options: []>]
cannot be installed as binary packages and must be built from source.
Install the Command Line Tools:
  xcode-select --install

So I ran this to install the command line build tools:

rodney@rodneys-mini ~ % xcode-select --install
xcode-select: note: install requested for command line developer tools

This took several minutes as I had not updated my XCode in a while. No problem though. Then I went back and ran the command again, which installed a ton of dependencies.

rodney@rodneys-mini ~ % brew install postgis

That took a while.
