The use of "\d" inside psql will show ONLY constraints without any
embellishments similar to normal constraints. E.g.


ALTER TABLE ONLY a ADD CONSTRAINT achk CHECK (FALSE);

ALTER TABLE a ADD CONSTRAINT bchk CHECK (b > 0);

psql=# \d a      Table "public.a"Column |  Type   | Modifiers
--------+---------+-----------b      | integer |
Check constraints:   "achk" CHECK (false)   "bchk" CHECK (b > 0)

Is this acceptable? Or we need to put in work into psql to show ONLY
somewhere in the description? If yes, ONLY CHECK sounds weird, maybe
we should use LOCAL CHECK or some such mention:

Check constraints:   "achk" LOCAL CHECK (false)   "bchk" CHECK (b > 0)

Nikhils
