(the above is the result of a sample restore - the database is a simple database with very few records, and was backed up when no activity was taking place against it, unlike our production database).
 
Maybe I am using the wrong switches altogether to accomplish my end results.
 
Thanks a million for your willingness to point me in the right direction.

This command should produce a consistent dump of all the objects in the
database.  (Not a consistent view of each object in isolation, which is
AFAIU what you are saying.)

Next question is, how are you restoring this dump?
