Are you absolutely sure you did "CREATE VIEW" and not "CREATE TABLE" ?
PostgreSQL allows you to create a table by selecting from existing
tables. The sytax _exactly_ matches the create view syntax, except
for the single word TABLE vs. VIEW.
You can test this from pgsql with: \d mag_giacenza1_view
If it's a view, you'll see the column definitions, plus the parsed
version of the SELECT you used to create it.
If it's a table, you'll just see the column defines.
Which version of PostgreSQL are you using, BTW?
