Question

As per https://postgres.heroku.com/blog/past/2012/4/26/heroku_postgres_development_plan/ I did “heroku addons:add heroku-postgresql:dev”. But when I do

class CreateUsers < ActiveRecord::Migration 
  def up 
    create_table :users do |t| 
      execute "CREATE EXTENSION hstore" 
      t.hstore :access 
    end 
  end 

  def down 
    drop_table :users 
      execute "DROP EXTENSION hstore" 
    end 
  end
end

and then “heroku run rake db:migrate” I get this error:

PG::Error: ERROR: syntax error at or near “EXTENSION”
LINE 1: CREATE EXTENSION hstore ^
: CREATE EXTENSION hstore

Answer 1

finally got it to work. turns out i needed to “promote” the database using heroku pg:promote as per https://devcenter.heroku.com/articles/heroku-postgres-dev-plan
