除了已经找到的命令行\d+<table_name>之外，还可以使用info_schema.columns使用信息模式查找列数据

SELECT *
FROM info_schema.columns
WHERE table_schema = 'your_schema'
AND table_name   = 'your_table'

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

您可以使用此选项：

SELECT attname 
FROM pg_attribute,pg_class 
WHERE attrelid=pg_class.oid 
AND relname='TableName' 
AND attstattarget <>0; 

下面的命令可以简单地描述多个表

\dt <table> <table>

下面的命令可以详细描述多个表：

\d <table> <table>

下面的命令可以更详细地描述多个表：

\d+ <table> <table>

除了已经找到的命令行\d+<table_name>之外，还可以使用info_schema.columns使用信息模式查找列数据

SELECT *
FROM info_schema.columns
WHERE table_schema = 'your_schema'
AND table_name   = 'your_table'

尝试以下操作（在psql命令行工具中）：

\d+ tablename
