Обсуждение: Documentation enhancement

Hi,

I would like to suggest to enhance the documentation of the CREATE VIEW statement.

I think the fact that a "SELECT *" is internally stored as the expanded column list (valid at the time when the view
wascreated) should be documented together with the CREATE VIEW statement. Especially because the example does use
SELECT* to create the view. 

Regards
Thomas

Agreed.  The attached, applied patch documents this behavior.
