dumping recursive views broken in master

dumps as

CREATE VIEW sums_1_100 AS
WITH RECURSIVE t(n) AS (VALUES (1) UNION ALL SELECT (t_1.n + 1) FROM
t WHERE (t_1.n < 100)) SELECT sum(t.n) AS sum FROM t;

which doesn't load back, because of this missing FROM item "t_1".

Evidently, this is related to

Improve ruleutils.c's heuristics for dealing with rangetable aliases.

Oops. I'll take a look.
