Run Postgres if not running

[croaky]

The laptop script currently installs, but does not run or set a plist file for Postgres. For the Mac script, we should be able to grab the lines from brew info postgres. Not sure what to use for the if statement.

"ps ux | grep postgres" ? or something to that effect. Brew installed stuff
runs under your account, right?

If it didn't, you'd do something like (as on debian) "ps u -u postgres"
or (probably better) "/etc/init.d/postgresql status" I wouldn't be
surprised if the command used to initialize the daemon under homebrew kept
the "status" target.

Homebrew instructions are:

initdb /usr/local/var/postgres -E utf8
ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

This issue and #243 more or less the same issue.

The initdb part appears to be handled by the Postgres formula now:

  def post_install
    unless File.exist? "#{var}/postgres"
      system "#{bin}/initdb", "#{var}/postgres"
    end
  end

Take a look at #254. I believe that is a pretty decent idempotent fix.
