您可以使用星号执行\d*搜索模式*，以查找与您感兴趣的搜索模式匹配的表。

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                        |

在MySQL中，DESCRIBE table_name

在PostgreSQL中，\d table_name

或者，可以使用以下长命令：

SELECT
        a.attname AS Field,
        t.typname || '(' || a.atttypmod || ')' AS Type,
        CASE WHEN a.attnotnull = 't' THEN 'YES' ELSE 'NO' END AS Null,
        CASE WHEN r.contype = 'p' THEN 'PRI' ELSE '' END AS Key,
        (SELECT substring(pg_catalog.pg_get_expr(d.adbin, d.adrelid), '\'(.*)\'')
                FROM
                        pg_catalog.pg_attrdef d
                WHERE
                        d.adrelid = a.attrelid
                        AND d.adnum = a.attnum
                        AND a.atthasdef) AS Default,
        '' as Extras
FROM
        pg_class c 
        JOIN pg_attribute a ON a.attrelid = c.oid
        JOIN pg_type t ON a.atttypid = t.oid
        LEFT JOIN pg_catalog.pg_constraint r ON c.oid = r.conrelid 
                AND r.conname = a.attname
WHERE
        c.relname = 'tablename'
        AND a.attnum > 0

ORDER BY a.attnum

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。

/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

除了PostgreSQL方式（\d“something”或\dt“table”或\ds“sequence”等）

SQL标准方式，如下所示：

select column_name, data_type, character_maximum_length, column_default, is_nullable
from INFORMATION_SCHEMA.COLUMNS where table_name = '<name of table>';

它受到许多db引擎的支持。
