Postgresql 10 range partition

HI All,

                I would like to create a range partition table but my question is when create the partitions can I use for values less then?  If LESS THEN is not passable what is my options?  Here is what I try to do.

CREATE TABLE measurement (

    city_id                     int not null,

    MONTH_SID         integer not null,

    peaktemp              int,

    unitsales                 int

) PARTITION BY RANGE (MONTH_SID);

CREATE TABLE measurement_y2010 PARTITION OF measurement

    FOR VALUES LESS THEN (201007)

NOTE: Any month_SID values less than 2010 July

CREATE TABLE measurement_y2011 PARTITION OF measurement

    FOR VALUES LESS THEN (201107)

NOTE: Any month_SID values between 2010 July  and 2011 June

….

Skip here

….

CREATE TABLE measurement_y2017 PARTITION OF measurement

    FOR VALUES LESS THEN (201707)

NOTE: Any month_SID values between 2016 July  and 2017 June

CREATE TABLE measurement_y2018 PARTITION OF measurement

    FOR VALUES LESS THEN (201807)

NOTE: Any month_SID values between 2017 July  and 2018 June

Thank you very much for your input,

Garry
