Subject: one column from huge view

Hello.
I've googled a bit but I think I can't match the keywords, so I thought
I'll ask here:
Let's say I've got a view with 100 columns and 1mln rows; some of them are
calculated "on the fly". For some reason I want only one column from
this view:
select col1 from huge_view;
Now, does PostgreSQL skip all the calculations from other columns and
executes this query faster then select * from huge_view?
