Rod,
this arguments are quite academic. On one side, this could be 
restricted, thats what pg_depends is good for (this already happens for 
inherited tables).
On the other side, how often do you rename columns or tables?
On mssql, nobody cares. If you fool around with names, your views will 
be broken without warning. pgsql could be better easily.
I'd really prefer to have full view sources available rather than the 
gimmick of stable views despite renamed cols/tabs.
