如何获取所有对象的列表？ – PostgreSQL

我需要db中包含的对象列表：表,序列等…

获取表格列表是我唯一能够找到的.

我能用什么来获取一切的想法？

解决方法

您可以使用@R_411_4045@ION_SCHEMA表以及系统目录来执行此操作.

例如.,

列表序列

SELECT relname
FROM pg_class
WHERE relkind = 'S'
AND relnamespace IN (
    SELECT oid
    FROM pg_namespace
    WHERE nspname NOT LIKE 'pg_%'
    AND nspname != '@R_411_4045@ion_schema'
);

列表触发器

SELECT trg.tgname AS trigger_name
  FROM pg_trigger trg,pg_class tbl
 WHERE trg.tgrelid = tbl.oid
   AND tbl.relname !~ '^pg_';
-- or
SELECT tgname AS trigger_name
  FROM pg_trigger
 WHERE tgname !~ '^pg_';

-- with @R_411_4045@ION_SCHEMA:

SELECT disTINCT trigger_name
  FROM @R_411_4045@ion_schema.triggers
 WHERE trigger_schema NOT IN
       ('pg_catalog','@R_411_4045@ion_schema');
