Yes, the has_xxxxxx_privileges() family should be added later or soon.
Anyway, what I wanted to say is we have no special functions to show
owner of the database objects.

Indeed, I put the "largeobject_compat_acl" in the compatibility section,
but no other GUCs have "compat" prefix/suffix. It seems to me fair enough.

An other alternative is "largeobject_check_acl". What's your feeling?
