The error message means exactly what it says.
As of v11 it'll be possible to grant usage of lo_export() to non-superusers, but in all released branches that check is hard-wired.
Note that since you can use that function to overwrite PG data or config files, granting use of it to someone you wouldn't trust with full superuser would be a damfool idea anyway.
