与DESCRIBE TABLE等效的psql是\d TABLE。

有关详细信息，请参阅PostgreSQL手册的psql部分。

如果您想从查询而不是psql获取它，可以查询目录模式。下面是一个复杂的查询，它可以做到这一点：

SELECT  
    f.attnum AS number,  
    f.attname AS name,  
    f.attnum,  
    f.attnotnull AS notnull,  
    pg_catalog.format_type(f.atttypid,f.atttypmod) AS type,  
    CASE  
        WHEN p.contype = 'p' THEN 't'  
        ELSE 'f'  
    END AS primarykey,  
    CASE  
        WHEN p.contype = 'u' THEN 't'  
        ELSE 'f'
    END AS uniquekey,
    CASE
        WHEN p.contype = 'f' THEN g.relname
    END AS foreignkey,
    CASE
        WHEN p.contype = 'f' THEN p.confkey
    END AS foreignkey_fieldnum,
    CASE
        WHEN p.contype = 'f' THEN g.relname
    END AS foreignkey,
    CASE
        WHEN p.contype = 'f' THEN p.conkey
    END AS foreignkey_connnum,
    CASE
        WHEN f.atthasdef = 't' THEN d.adsrc
    END AS default
FROM pg_attribute f  
    JOIN pg_class c ON c.oid = f.attrelid  
    JOIN pg_type t ON t.oid = f.atttypid  
    LEFT JOIN pg_attrdef d ON d.adrelid = c.oid AND d.adnum = f.attnum  
    LEFT JOIN pg_namespace n ON n.oid = c.relnamespace  
    LEFT JOIN pg_constraint p ON p.conrelid = c.oid AND f.attnum = ANY (p.conkey)  
    LEFT JOIN pg_class AS g ON p.confrelid = g.oid  
WHERE c.relkind = 'r'::char  
    AND n.nspname = '%s'  -- Replace with Schema name  
    AND c.relname = '%s'  -- Replace with table name  
    AND f.attnum > 0 ORDER BY number
;

它非常复杂，但它确实向您展示了PostgreSQL系统目录的强大和灵活性，并将帮助您掌握pg_catalog；-）。请确保更改查询中的%s。第一个是Schema，第二个是表名。

您可以使用psql斜杠命令执行此操作：

 \d myTable describe table

它也适用于其他对象：

 \d myView describe view
 \d myIndex describe index
 \d mySequence describe sequence

/dt是列出数据库中所有表的命令。使用/d命令和/d+，我们可以获得表的详细信息。sysntax将如下所示*/d table_name（或）\d+table_name

Use this command 

\d table name

like 

\d queuerecords

             Table "public.queuerecords"
  Column   |            Type             | Modifiers
-----------+-----------------------------+-----------
 id        | uuid                        | not null
 endtime   | timestamp without time zone |
 payload   | text                        |
 queueid   | text                        |
 starttime | timestamp without time zone |
 status    | text                        |

您也可以使用以下查询进行检查

Select * from schema_name.table_name limit 0;

示例：我的表有两列名称和pwd。下面是截图。

*使用PG admin3
