【问题描述】：

如上所述，我想列出所有用户 + 他们的架构（他们在哪里获得了 USAGE 权限）。

所以我差不多完成了，

让我告诉你我得到了什么：

SELECT 
    u.usesysid as idUser, 
    u.usename as login,
    u.passwd as password,
    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 member_of,
     ARRAY(SELECT nspname
        FROM pg_namespace pn,pg_catalog.pg_roles b
        JOIN pg_catalog.pg_auth_members m ON (m.member = b.oid)
        WHERE pg_catalog.has_schema_privilege(b.rolname, nspname, 'USAGE')= true
        AND m.member = r.oid
        AND nspname <> 'information_schema'
        AND nspname !~~ 'pg\_%') as usage_schemas
FROM 
    pg_catalog.pg_roles r
JOIN 
    pg_catalog.pg_user u on(r.rolname=u.usename)
WHERE
    usename !~ 'postgres'
ORDER BY
    1;

这是我得到的： https://image.noelshack.com/fichiers/2019/38/5/1568980459-capture5.png

这就是我想要的： https://image.noelshack.com/fichiers/2019/38/5/1568967833-capture4.png

谁能帮帮我？

这是正确的：

SELECT
    u.usesysid as idUtilisateur,
    u.usename as login,
    u.passwd as motDePasse,
    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 groupes,
    ARRAY(SELECT nspname
        FROM pg_namespace pn
        WHERE pg_catalog.has_schema_privilege(r.rolname, nspname, 'USAGE')= true
        AND nspname <> 'information_schema'
        AND nspname !~~ 'pg_%') as schemas
FROM
    pg_catalog.pg_roles r
JOIN
    pg_catalog.pg_user u on(r.rolname=u.usename)
WHERE
    usename !~ 'postgres'
ORDER BY 
    1;
