Description:        

Hello PostgreSQL team,
I found an error in the view definition SQL given when looking at the view
description using \d+. Here are the detailed steps for this problem.
executed query:
postgres=#  CREATE TABLE onek (thousand int4);
CREATE TABLE
postgres=#  CREATE VIEW limit_thousand_v_3 AS SELECT thousand FROM onek
WHERE thousand < 995  ORDER BY thousand FETCH FIRST (NULL::bigint +
1::bigint) ROWS WITH TIES;
CREATE VIEW
postgres=#  \d+ limit_thousand_v_3
                      View "public.limit_thousand_v_3"
  Column  |  Type   | Collation | Nullable | Default | Storage | Description
----------+---------+-----------+----------+---------+---------+-------------
 thousand | integer |           |          |         | plain   |
View definition:
 SELECT thousand
   FROM onek
  WHERE thousand < 995
  ORDER BY thousand
 FETCH FIRST NULL::bigint + 1::bigint ROWS WITH TIES;
postgres=# SELECT thousand
postgres-#    FROM onek
postgres-#   WHERE thousand < 995
postgres-#   ORDER BY thousand
postgres-#  FETCH FIRST NULL::bigint + 1::bigint ROWS WITH TIES;
ERROR:  syntax error at or near "::"
LINE 5:  FETCH FIRST NULL::bigint + 1::bigint ROWS WITH TIES;
                         ^
I think that executing the view definition query will be successful.
I'm happy to provide more info if I can/ if needed.
Thanks,
