Description:

Hi,


I'm testing the Materialized View.
When I've tried to create materialized view with specified column_name, I
got an ERROR.


example:
- Creating original table
CREATE TABLE t ( i int );


- Creating materialized view with column_name
CREATE MATERIALIZED VIEW mv_t(ii) AS SELECT * FROM t;


And then, I got a bellow ERROR.
----
ERROR:  SELECT rule's target entry 1 has different column name from "ii"
----


I did not get any ERROR with non materialized view.
CREATE VIEW mv_t(ii) AS SELECT * FROM t;


Is this a bug or restriction for Materialized View?


regards,
