How to reuse a large query without repeating it?

Question

If I have two queries, which I will call horrible_query_1 and ugly_query_2, and I want to perform the following two minus operations on them:

Answer 1

create view horrible_query_1_VIEW as 
 select .. ...
  from .. .. ..

create view ugly_query_2_VIEW as 
 select .. ...
  from .. .. ..

Then

(horrible_query_1_VIEW) minus (ugly_query_2_VIEW)

(ugly_query_2_VIEW) minus (horrible_query_1_VIEW)

Or, maybe, with a with clause:

with horrible_query_1 as (
  select .. .. ..
    from .. .. ..
) ,
ugly_query_2 as (
  select .. .. ..
     .. .. ..
)
(select * from horrible_query_1 minus select * from ugly_query_2    ) union all
(select * from ugly_query_2     minus select * from horrible_query_1)
