When running rake db:reset you might get one of the following informative errors:

  function public.gen_random_uuid() does not exist

  db/structure.sql:22: ERROR:  schema "public" already exists

To fix them tell Ruby to dump everything by editing config/application.rb:

module XXX
  class Application < Rails::Application
    config.active_record.dump_schemas = :all

Tested with Rails 6.
