Hi Team,

I found something weird. Restoring a view fails if this view contains an
attribute without alias name.

Please find below the details to reproduce the problem: 

    psql -h localhost -c 'CREATE DATABASE demo;'

    psql -h localhost -d demo
    
    demo=# CREATE VIEW v_static_select as 
    WITH static_select as (
        select 
            1  as foo,
            'text'
    )
    select * from static_select;
    
    
    demo=# \d+ v_static_select 
                            View "public.v_static_select"
      Column  |  Type   | Collation | Nullable | Default | Storage  |
Description 

----------+---------+-----------+----------+---------+----------+-------------
     foo      | integer |           |          |         | plain    | 
     ?column? | text    |           |          |         | extended | 
    View definition:
     WITH static_select AS (
             SELECT 1 AS foo,
                'text'::text
            )
     SELECT static_select.foo,
        static_select."?column?"
       FROM static_select;


    demo=# select * from v_static_select;
    foo | ?column? 
    -----+----------
    1 | text
    (1 row)


    pg_dump -h localhost -p5432 -U postgres -d demo -Fc -f /tmp/demo.dump

    psql -h localhost -p5432 -U postgres -d demo -c 'DROP VIEW
v_static_select ;'

    pg_restore -s -h localhost -p5432 -U postgres -d demo  /tmp/demo.dump 
    
    pg_restore: error: could not execute query: ERROR:  column
static_select.?column? does not exist
    LINE 7:     static_select."?column?"
            ^
    Command was: CREATE VIEW public.v_static_select AS
     WITH static_select AS (
         SELECT 1 AS foo,
            'text'::text
        )
     SELECT static_select.foo,
        static_select."?column?"
       FROM static_select;
