Using multiple postgresql version with appropoiate psql and other pg tools version on mac with postgresapp

First make sure no postgres instance is configured to run on startup. And you get nothing when you run this command: which -a psql This is to make sure you don't have anything related to postgres in your PATH, which can conflict. If you do get some hits with above command, you have to manually either remove the installed versions of postgres or just fix PATH and remove ref to that path which has these binaries(psql, pg_dump etc)

For me, i was using brew installed postgres, i had to just comment out a PATH editing line which was inserted by brew in my .bash_profile

Lifecycle callbacks

initialize: once, when the controller is first instantiated
connect: anytime the controller is connected to the DOM

UPDATE: You don't need shims anymore! We can just use this now, and eventually it'll even be in Ember core.

app.import() works with node_modules now! As of Ember 2.15. Previously it only worked with bower_components and vendor.

Docs for app.import are here: https://ember-cli.com/managing-dependencies#standard-non-amd-asset
