What does the owner column refer to? A database user? If so, then
you could use a trigger that checks CURRENT_USER or SESSION_USER
and raises an exception if the user doesn't have permission to
update or delete the affected row. In the PostgreSQL documentation,
see the "Triggers" chapter and the "Trigger Procedures" section of
the "PL/pgSQL - SQL Procedural Language" chapter.
