Well, yes, but that's no longer the issue.  I guess my thought was that
if we could get the common id space change in before 8.0 then group
ownership could possibly be introduced in 8.1 w/o having to do a
dump/restore.  I'm still relatively new to Postgres, is it normal to
require a dump/restore between semi-major (8.0 to 8.1) revisions?  If so
then it doesn't matter since I wouldn't expect group ownership to be
introduced prior to 8.1 (at the earliest..) anyway.
