In postgresql a view is in fact a relation just like a table is a
relation, except that the view has an "on select do instead .." trigger
attached to it (don't take the syntax literally, I'm writing this from
memory).

Same effect as using a view, except with a view you would also have a
trigger associated with select so you can select and insert into the same
relation.
