如何在 PostgreSQL 中使用分区内分区（多级分区或分区的分区）

Question

如何在PostgreSQL中使用partition inside partition 我想在 PostgreSQL 中做多级分区就像第一个 table 列 id 和第二个分区 table 列日期所以这将是三级层次结构

Answer 1

这篇文章用例子很好地解释了这一点 https://joaodlf.com/postgresql-10-partitions-of-partitions.html

CREATE TABLE dt_totals (
    dt_total date NOT NULL,
    geo varchar(2) not null,
    impressions integer DEFAULT 0 NOT NULL,
    sales integer DEFAULT 0 NOT NULL
)
PARTITION BY RANGE (dt_total);

CREATE TABLE dt_totals_201801
PARTITION OF dt_totals
FOR VALUES FROM ('2018-01-01') TO ('2018-01-31');

CREATE TABLE dt_totals_201801
PARTITION OF dt_totals
FOR VALUES FROM ('2018-01-01') TO ('2018-01-31')
PARTITION BY LIST (geo);

CREATE TABLE dt_totals_UK_201801 PARTITION OF dt_totals_201801 FOR VALUES IN ('UK');
CREATE TABLE dt_totals_US_201801 PARTITION OF dt_totals_201801 FOR VALUES IN ('US');
CREATE TABLE dt_totals_AU_201801 PARTITION OF dt_totals_201801 FOR VALUES IN ('AU');
