Bug reference:      6049

Operating system:   Linux (Fedora 12)
Description:        Can't load dumped view with VALUES and ORDER BY
Details:

If you create a view based on a VALUES statement with an ORDER BY clause,
the SQL produced by pg_dump can't be loaded back into the database.

$ createdb testdb
$ psql -c "CREATE VIEW test_view AS VALUES (1), (2), (3) ORDER BY 1; -- or
ORDER BY column1" testdb
CREATE VIEW
$ pg_dump -t test_view testdb > test_view.dump
$ psql -c "DROP VIEW test_view;" testdb
DROP VIEW
$ psql -f test_view.dump testdb

psql:test_view.dump:18: ERROR:  invalid reference to FROM-clause entry for
table "*VALUES*"
LINE 2:     VALUES (1), (2), (3) ORDER BY "*VALUES*".column1;
                                          ^
HINT:  There is an entry for table "*VALUES*", but it cannot be referenced
from this part of the query.
psql:test_view.dump:21: ERROR:  relation "public.test_view" does not exist

Here's the definition that gets dumped:

CREATE VIEW test_view AS
    VALUES (1), (2), (3) ORDER BY "*VALUES*".column1;
