Well, yeah.  The one you created is not the "standard" public schema;
it might happen to have the same name, but claiming it is the same
object seems very confused.  It won't necessarily have the same
ownership or permissions, and it definitely won't have the same
comment unless you add that.

As far as I know, pg_dump deals with this issue for the standard
public schema.  For user-created objects, it's up to you to be sure
that the restoring user has sufficient permissions.  This is not
different for schemas than for any other objects.

I'm not really seeing a bug here, and you haven't provided sufficient
detail about your actual problem to act on it.
