Rails 5 - db:environment:set

Rails
1

I am in the process of upgrading an app to Rails 5. One thing that I
stumbled on while recreating my test database was the
db:environment:set
command.

From what I can see, this makes a table named internal_metadata and
stores an environment value.

Is running this command on all existing databases required? I cannot
find
any further information about this command in the upgrade guide or the
ActiveRecord changelog notes.

Looks like this is for preventing accidental destruction of the
production
DB:
