I am wondering how to partition a table like,

  • from 0 to 100
  • from 100 to 200
  • 200 and above
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);

To soecify a range that has no upper limit, use

FOR VALUES FROM (150) TO (MAXVALUE)
