psql \du no more showing "member of" column

[Luca Ferrari <fluca1978@xxxxxxxxx>]

Hi all,
in version 16 psql does not show anymore the "member of" group
information when showing users with \du.

The query (still working fine) in previous versions was:

SELECT r.rolname, r.rolsuper, r.rolinherit,
 r.rolcreaterole, r.rolcreatedb, r.rolcanlogin,
 r.rolconnlimit, r.rolvaliduntil,
 ARRAY(SELECT b.rolname
       FROM pg_catalog.pg_auth_members m
       JOIN pg_catalog.pg_roles b ON (m.roleid = b.oid)
       WHERE m.member = r.oid) as memberof
, r.rolreplication
, r.rolbypassrls
FROM pg_catalog.pg_roles r
WHERE r.rolname !~ '^pg_'
ORDER BY 1;


while now it is:

SELECT r.rolname, r.rolsuper, r.rolinherit,
 r.rolcreaterole, r.rolcreatedb, r.rolcanlogin,
 r.rolconnlimit, r.rolvaliduntil
, r.rolreplication
, r.rolbypassrls
FROM pg_catalog.pg_roles r
WHERE r.rolname !~ '^pg_'
ORDER BY 1;


at least, as it is shown by `psql -E`.
I wonder why this information has been removed, I'm not able to find
this in the documentation.

Thanks,
Luca
