I have no big interest in changing that right now. It doesn't impact
any of the points at issue.

I didn't either. After working on it some more, what I want to do now
is keep the ACL representation the same as it is, but implicitly assume
that the owner has all grant options whether the ACL says so or not.
The "other callers" I was referring to above are the undocumented
aclinsert() and aclremove() functions, which I propose changing to
add an owner's-UID parameter to. Neither of these are actually used
anywhere, so it might make more sense to just remove 'em. We'd also
need to change aclcontains(), which is used in the information_schema
views.
With this code base it would not really matter whether default ACLs
include the owner's grant options or not. I am inclined to the view
that they should not, so as to minimize clutter in the \z display.
One could argue that the owner doesn't really have grant options in the
normal sense anyway, the normal sense being a revocable right, which
these are not.
I have a preliminary patch for this, which I will post later --- it
needs some more work yet. (I only just realized the need to do
something with aclcontains... at the moment the information_schema
in my patched version is showing that the owner doesn't have grant
options, which is probably not what we want it to say.)
