postgresql - Postgres 11 FDW 找不到分区表

Question

尝试使用 postgres 11 外部数据包装器访问分区表。我可以访问基础表但不能访问表。

create schema foo;

CREATE TABLE foo.test1 (
    city_id         int not null,
    logdate         date not null,
    peaktemp        int,
    unitsales       int
) PARTITION BY RANGE (logdate);

CREATE TABLE foo.measurement1_y2006m02 PARTITION OF foo.test1
    FOR VALUES FROM ('2006-02-01') TO ('2006-03-01');

CREATE TABLE foo.measurement1_y2006m03 PARTITION OF foo.test1
    FOR VALUES FROM ('2006-03-01') TO ('2006-04-01');

insert into foo.measurement1_y2006m02 values (1,'2006-02-15',1,1);
insert into foo.measurement1_y2006m03 values (2,'2006-03-15',2,2);

select * from foo.test1;

这似乎没问题。然后我创建一个链接:

DROP SCHEMA IF EXISTS fdw_foo CASCADE;
CREATE SCHEMA fdw_foo;
IMPORT FOREIGN SCHEMA foo
    FROM SERVER myserver INTO fdw_foo;

这个有效:

select * from fdw_foo.measurement1_y2006m02;

这不是

select * from fdw_foo.test1;

ERROR: relation "fdw_foo.test1" does not exist

有什么想法吗？

这是您应该报告的错误。

作为解决方法，您可以自己创建外部表:

CREATE FOREIGN TABLE fdw_foo.test1 (
    city_id         int not null,
    logdate         date not null,
    peaktemp        int,
    unitsales       int
) SERVER myserver
OPTIONS (schema_name 'foo', table_name 'test1');
