查询格式：

SELECT c.relname 表名称, A.attname AS 字段名称, col_description(A.attrelid,A.attnum) AS 注释, format_type ( A.atttypid, A.atttypmod ) AS 类型, CASE WHEN A.attnotnull='f' THEN '否' ELSE '是' END AS 是否必填, a.attnum 序号FROM pg_class AS c, pg_attribute AS aWHERE A.attrelid = C.oid AND A.attnum > 0 ORDER BY c.relname,a.attnum;

查询示例：

SELECT c.relname 表名称, A.attname AS 字段名称, split_part(col_description ( A.attrelid, A.attnum ),'：',1) AS 注释, format_type ( A.atttypid, A.atttypmod ) AS 类型, CASE WHEN A.attnotnull='f' THEN '否' ELSE '是' END AS 是否必填, a.attnum 序号FROM pg_class AS c, pg_attribute AS aWHERE c.relnamespace=16389 AND c.relname not like 'v_%' AND c.relname not like 'pk_%' AND c.relname not like 'unidx%' AND c.relname not like '%_index' AND c.relname not like '%_seq' AND c.relname not like '%_pkey' AND A.attrelid = C.oid AND A.attnum > 0 ORDER BY c.relname,a.attnum;

查询效果：

补充：postgresql 查询某一个表中的所有字段

postgresql 查询某一个表中的所有字段，也就是查询所有的列名

select * from information_schema.columnswhere table_schema='public' and table_name='表名称 ';

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。如有错误或未考虑完全的地方，望不吝赐教。
