Interval Partitioning Example
edb=# CREATE TABLE sales (prod_id int, prod_quantity int, sold_month date)
edb-# PARTITION BY RANGE (sold_month) INTERVAL (NUMTOYMINTERVAL(1,'MONTH')) (
edb(# PARTITION jan VALUES LESS THAN ('31-JAN-2019'),
edb(# PARTITION feb VALUES LESS THAN ('28-FEB-2019'));
CREATE TABLE
edb=# d+ sales
Partitioned table "public.sales"
Column | Type | Collation | Nullable | Default | Storage | Stats target |
Description
---------------+-----------------------------+-----------+----------+---------+---------+--------------+------
--
prod_id | integer | | | | plain | |
prod_quantity | integer | | | | plain | |
sold_month | timestamp without time zone | | | | plain | |
Partition key: RANGE (sold_month) INTERVAL ('1 mon'::interval)
Partitions: sales_feb FOR VALUES FROM ('31-JAN-19 00:00:00') TO ('28-FEB-19 00:00:00'),
sales_jan FOR VALUES FROM (MINVALUE) TO ('31-JAN-19 00:00:00')
edb=# INSERT INTO sales VALUES (1,1000,'10-JAN-2019');
INSERT 0 1
edb=# INSERT INTO sales VALUES (2,100000,'25-FEB-2019');
INSERT 0 1

Interval Partitioning Example
--when new month entry came it will automatically create a partition for that month and insert into it.
edb=# INSERT INTO sales VALUES (1,19000,'05-MAR-2019');
psql: NOTICE: Low value ('28-FEB-19 00:00:00') High value ('28-MAR-19 00:00:00')
INSERT 0 1
edb=# d+ sales
