Heroku CLI v3.0.0 released replacing db:push/pull with pg:push/pull
Change effective on 30 September 2013
A new version of the Heroku CLI is available that removes the db:push and db:pull commands, replacing them with pg:push and pg:pull. These new commands are faster and significantly more robust but no longer support non-Postgres databases. For help installing Postgres locally see local Postgres setup in Dev Center.
Detailed information on these new commands can be found in the pg:push and pg:pull section of the Heroku Postgres documentation.
Update your Toolbelt and push and pull your Postgres databases.
