Postgres 按范围从 x 及以上条件分区

Postgres partition by range from x and above condition

我想知道如何对 table 进行分区，

从 0 到 100
从 100 到 200
200 及以上

CREATE TABLE grade_main 
(
    id serial not null, 
    g int not null
) partition by range (g);

CREATE TABLE grade_00_100 PARTITION OF grade_main FOR VALUES FROM (0) TO (100);
CREATE TABLE grade_100_200 PARTITION OF grade_main FOR VALUES FROM (100) TO (200);

-- The following returns syntax error

CREATE TABLE grade_150_all PARTITION OF grade_main FOR VALUES FROM (150);

要指定没有上限的范围，请使用

FOR VALUES FROM (150) TO (MAXVALUE)
