Heroku CLI PostgreSQL Command Changes

Change effective on 08 December 2016

In the Heroku CLI, we’ve updated the heroku-pg plugin to 2.0.0. This is a rewrite of the codebase and moves everything from ruby to node. Some UX changes have been made to the output such as the usage of color.

Because the new CLI commands have a standard for subcommands that heroku pg:* was not following, the commands for backups, maintenance and links: heroku pg:backups *, heroku pg:maintenance [run|window] and heroku pg:links [create|destroy] have been changed to heroku pg:backups:*, heroku pg:maintenance:[run|window] and heroku pg:links:[create|destroy].
