In my application one of my models uses a HStore but when I create the extension HStore it fails with the following error:
PG::Error: ERROR: syntax error at or near "EXTENSION" LINE 1: CREATE EXTENSION hstore; ^ : CREATE EXTENSION hstore; I'm using heroku's free database, as this is just a development deployment so I get the hang of how things work with deploying on heroku. This doesn't fail in my development environment. So whats causing it to fail?
