Thanks for the new version. All previous issues I raised have been resolved.

I have an inconsistency to note between VIEWs and MATERIALIZED VIEWs:

CREATE VIEW v_test8 (meow, "?column?") AS SELECT 1 bark, 2;
CREATE MATERIALIZED VIEW mv_test8 (meow, "?column?") AS SELECT 1 bark, 2;

pg_dump output:

CREATE VIEW v_test8 AS
SELECT 1 AS meow, 2;

CREATE MATERIALIZED VIEW mv_test8 (
meow,
"?column?"
) AS
SELECT 1 AS meow, 2
WITH NO DATA;

The materialized view adds in column name parameters, whereas the
standard view doesn't. But it seems to add column parameters
regardless:

CREATE VIEW v_test9 AS SELECT 1;
CREATE MATERIALIZED VIEW v_test9 AS SELECT 1;

CREATE VIEW v_test9 AS
SELECT 1;

CREATE MATERIALIZED VIEW mv_test9 (
"?column?"
) AS
SELECT 1
WITH NO DATA;

VIEWs never seem to use column parameters, MATERIALIZED VIEWs always
appear to use them.
