I understand the practicality of what you're saying.  However, I'm
curious about where your definition of views comes from.  My
understanding is that update-able views were concepts of Codd's
original relational model and such views are also part of the SQL
standard.

And since "PostgreSQL prides itself in standards compliance...,"
(http://www.postgresql.org/about/) I wouldn't expect to see
update-able views on the features *not* to do list any time soon.
(http://wiki.postgresql.org/wiki/Todo#Features_We_Do_Not_Want)

Although I do see planner hints are one of the features listed there.
