Oddly enough, it's the same thing. There's schema, the object, which
holds related objects inside it. databases contain schemas which
contain tables, indexes, etc...
Then there's schema, as a definition of how something it put together.
Confusing, I know.
The easiest way to view the sql format definition of a view is the use
the pg_views view...
select * from pg_views where viewname='nameofview';
You can get the same thing with pg_dump:
pg_dump dbname -s -t tableorindexname
