yes. it is a feature that not many DBMS support (i know only of MySQL
which supports inserting a column at a defined splace - and don't blame
me - i don't like MySQL either) - it is a feature that's missing in many
DBMS too.

I don't know about PostGreSQL, but views can be slower than normal
queries - especially when you don't do a "select * form view" but add a
some where-clauses, joins etc.
