Heroku - PGError: ERROR: syntax error at or near "ENGINE"

Question

I am trying to run

heroku rake db:migrate

to run my migrations on heroku and the first two migrations ran great but the third which looks like this

create_table :charities, :options => "ENGINE=MyISAM" do |t|
  t.string :name,               :null => false
  t.string :title,              :null => false
  t.timestamps
end

add_index :charities, :name
add_index :charities, :title

Answer 1

Heroku uses PostgreSQL, and MyISAM engine is MySQL-specific. I suggest you remove that part. Or, add checking on what database is used and make that optional.

Here's a link to how to check the database.
