Open PgAdmin 4

#!/usr/bin/env ruby

=begin
PgAdmin 4 runs on a random port. Once you close its browser window, there
is no way to get back to it. But it stores its address in a hidden file.
This script finds the file and opens the address inside in a default
browser.

path = File::expand_path('~')
filename = Dir.new(path).entries.find do |item|
  item.match?(/^\.pgAdmin4\.\d+\.addr$/)

addr = File.read(filename).chomp
