直接切換到對應的庫下執行
select
nsp.nspname as SchemaName
,cls.relname as ObjectName
,rol.rolname as ObjectOwner
,case cls.relkind
when r then TABLE
when m then MATERIALIZED_VIEW
when i then INDEX
when S then SEQUENCE
when v then VIEW
when c then TYPE
else cls.relkind::text
end as ObjectType
from pg_class cls
join pg_roles rol
on rol.oid = cls.relowner
join pg_namespace nsp
on nsp.oid = cls.relnamespace
where nsp.nspname not in (information_schema, pg_catalog)
and nsp.nspname not like pg_toast%
and rol.rolname = rw
order by nsp.nspname, cls.relname;
注意,這個不能獲取到schema和database的歸屬情況,只能獲取到表和序列的objectowner的情況
上面的這個sql,能查出下面的這種rolname=objectowner歸屬的
schemaname | objectname | objectowner | objecttype
------------+------------+-------------+------------
public | sq1l | rw | SEQUENCE
public | t1 | rw | TABLE
對于下面的這2種情況,都查不出來的。
1、表的owner是一個role,表里面access privilege又有其它的授權
2、非public的schema下
db2=# create schema myschema;
db1=# alter schema myschema owner to rw;
db1=# /dn
List of schemas
Name | Owner
----------+----------
myschema | rw
public | postgres
(2 rows)
db2=# /d
List of relations
Schema | Name | Type | Owner
--------+------+-------+----------
public | tt | table | postgres
(1 row)
db2=# /z tt
Access privileges
Schema | Name | Type | Access privileges | Column privileges | Policies
--------+------+-------+---------------------------+-------------------+----------
public | tt | table | postgres=arwdDxt/postgres+| |
| | | dts=arwdDxt/postgres | |
(1 row)
