DROP OWNED BY

I'm working on the promised DROP OWNED patch, and just noticed that it
needs modifications to the Grant/Revoke machinery that are too invasive
to consider for 8.1; the problem is that ExecuteGrantStmt takes textual
names for objects and grantees, and what I have from pg_shdepend are
Oids.  Dropping the objects themselves is easy -- the problem is
dropping grants to other objects.

So, instead of doing that, I think it's better to convert the Oids to
names in the shared-dependency code.  This should be rewritten after the
next development period starts, for efficiency and cleanliness.

Is anyone opposed to this idea?  Further, is anyone opposed to the
addition as a whole?  I'm already a month and a half late with this
part of the shdep patch, so if people think it's better to ship this
release without it, so be it.  (Of course I don't like that.)
