Yes, and have the actual 'description' field (as it's variable) at the
end of the catalog.
Regarding the semantics of it- I was thinking about how directories and
unix files work. Basically, adding or removing a sub-object would
update the alter time on the object itself, changing an already existing
object or sub-object would update only the object/sub-object's alter
time. Creating an object or sub/object would set its create time and
alter time to the same value. I would distinguish 'create' from
'ctime', however, and have our 'create' time be only the actual
*creation* time of the object. ALTER table OWNER TO user; would update
"table"s alter time.
Open to other thoughts on this and perhaps we should create a wiki page
to start documentating the semantics. Once we get agreement there, it's
just a bit of code. :)
Thanks,
Stephen
