May be possible to reach a agreement on the sentence form. Similar
descriptions used for referential constraints in the \d command:

create table t1 (id int primary key);create table t2 (id int references
t1(id));\d t2                 Table "public.t2" Column |  Type   |
Collation | Nullable | Default
--------+---------+-----------+----------+--------- id     | integer
|           |          | Foreign-key constraints:    "t2_id_fkey"
FOREIGN KEY (id) REFERENCES t1(id)As for tabular form it looks more
natural to have a separate psql command for pg_auth_members system
catalog. Something based on this query:SELECT r.rolname role, m.rolname
member,       admin_option admin, inherit_option inherit, set_option
set,       g.rolname grantorFROM pg_catalog.pg_auth_members pam     JOIN
pg_catalog.pg_roles r ON (pam.roleid = r.oid)     JOIN
pg_catalog.pg_roles m ON (pam.member = m.oid)     JOIN
pg_catalog.pg_roles g ON (pam.grantor = g.oid)WHERE r.rolname !~
'^pg_'ORDER BY role, member, grantor;       role       |     
member      | admin | inherit | set |     grantor
------------------+------------------+-------+---------+-----+------------------ regress_du_role0

regress_du_role2 | f     | t       | t   |

f   | regress_du_role2 regress_du_role1 | regress_du_admin | t     |
t       | t   | postgres regress_du_role1 | regress_du_role2 | t     |
f       | t   | regress_du_admin regress_du_role2 | regress_du_admin |
t     | t       | t   | postgres(10 rows)But is it worth inventing a new
psql command for this?
