It makes sense to me.

The long description is a bit confusable, because it does not disable all the
privilege checks, such as lo_export/lo_import which already checks superuser
privilege on execution in the earlier releases.
What's your opinion about:
long desc: When turned on, privilege checks on large objects perform with
backward compatibility as 8.4.x or earlier releases.
