Roles (groups) in PostgreSQL DBMS

A role is an entity that can own objects and have certain rights in the database;

The CerebroSQL program introduced the separation of "Roles" for which it is forbidden to connect to the database (the login privilege was not granted) - they are displayed in the ROLES node and "Roles" for which connection to the database is allowed - are displayed in the USER node

SELECT r.oid, r.rolname,
r.rolsuper::int,
r.rolinherit::int,
r.rolcreaterole::int,
r.rolcreatedb::int,
r.rolcanlogin::int,
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)::text as memberof,
pg_catalog.shobj_description(r.oid, 'pg_authid') AS description,
r.rolreplication::int,

FROM pg_catalog.pg_roles r
where rolcanlogin = false
ORDER BY 1
