# In Rails 5.2 the `load_config` task was made dependent on `environment`
# to enable credentials reading, see https://github.com/rails/rails/pull/31135
# This causes the whole app to initialize before `db:create` and that
# causes a database connection for observers, sphinx and maybe others.
# For MySQL where database name is part of connection URL, this causes a
# connection failure and thus failure to create the database.
# Since we don't use credentials, we can remove that dependency.
# And then a whole mess to fix other use cases especally db:reset
