def each_schema_load_environment
# If we're in development, also run this for the test environment.
# This is a somewhat hacky way to do this, so here's why:
# 1. We have to define this before we load the schema, or we won't
# have a timestamp_id function when we get to it in the schema.
# 2. db:setup calls db:schema:load_if_ruby, which calls
# db:schema:load, which we define above as having a prerequisite
# of this task.
# 3. db:schema:load ends up running
# ActiveRecord::Tasks::DatabaseTasks.load_schema_current, which
# calls a private method `each_current_configuration`, which
# explicitly also does the loading for the `test` environment
# if the current environment is `development`, so we end up
# needing to do the same, and we can't even use the same method
# to do it.
