  1. BUG #17675: pg_dump v15: Comments on constraints missing?

    The following bug has been logged on the website:

Bug reference:      17675
Logged by:          Franz-Josef Färber
Email address:      franz-josef.faerber@stmuk.bayern.de
PostgreSQL version: 15.0
Operating system:   postgres 15 container
Description:        

Hello,

unfortunately pg_dump Version 15 does not dump comments on constraints.
I tested inside the postgres:15 docker container:

CREATE DOMAIN year AS integer CONSTRAINT year_check CHECK (((VALUE >= 1900)
AND (VALUE <= 2100)));                      
COMMENT ON CONSTRAINT year_check ON DOMAIN year IS $$year check$$;          
                                           

CREATE TABLE t(x int, CONSTRAINT t_check CHECK(x>0));
COMMENT ON CONSTRAINT t_check ON t IS $$t check$$;    

pg_dump v15 won’t include both comments (whereas v14 does).
