postgreSQL有keep的使用吗

[道秋adol]

postgreSQL有想Oracle中keep的使用吗？
Oracle：

SELECT col,
MIN(value) KEEP(DENSE_RANK FIRST ORDER BY col) OVER(PARTITION BY col),
MAX(value) KEEP(DENSE_RANK LAST ORDER BY col) OVER(PARTITION BY col)
FROM tmp1
ORDER BY col;

postgres中可以用这个语句来做： select a.first_value,a.col from (select first_value(id)over(partition by col order by id desc),* from tmp1) as a;

mysql是没有 估计pg也差不多

mysql的功能太弱了，你这句话应该反过来说
