The data types are different, as one has the timestamp to (6) decimal
places after seconds.
development=# CREATE VIEW co AS SELECT LOCALTIMESTAMP::TIMESTAMP AS ov
WHERE FALSE;
CREATE VIEW
development=# CREATE TABLE link (ov TIMESTAMP);
CREATE TABLE
development=# CREATE OR REPLACE VIEW cod AS SELECT ov FROM link;
CREATE VIEW
development=# \d co
View "rbt.co"
Column | Type | Modifiers
--------+--------------------------------+-----------
ov | timestamp(6) without time zone |
View definition:
SELECT 'now'::text::timestamp(6) without time zone AS ov
WHERE false;
development=# \d cod
View "rbt.cod"
Column | Type | Modifiers
--------+-----------------------------+-----------
ov | timestamp without time zone |
View definition:
SELECT link.ov
FROM link;
