Couple Postgres View Questions - Mailing list pgsql-general

I have a couple questions about Postgres and Views.

I am curious about what Postgres actually does in regards to views and
the internal steps that it takes.

Are these the steps that it takes for each query that includes a view?
1. Dynamically Creates a Temp table with the view's select statement.
2. Executes the sql command against the view
3. Postgres destroys the temp table.


I understand that Postgres is not SQL 92 compliant with views because it
does not support updatable views.  Are there plans ever to support
updatable views?


Thanks,
Brian
