I agree with your disagreement.  This design is present in lots of
non-RDB systems - CVS, IMAP, PDA syncing,  etc.  It's clearly more
complicated, but can be made to work, and has been many times.  I don't
see anything about databases in general, or Postgres specifically, that
indicates it's a bad idea.
