I'm just curious...
If you have a view:
create foo_view as select * from foo;
Then you query it:
select * from foo_view;
What, behind the scenes, actually happens?
Is the definition of "foo_view" looked up in the system catalog, query
rewritten, parsed, then executed?
In other words, does the query *literally* get rewritten as:
select * from (select * from foo) as foo;
before it is parsed?
