Postgres 11 FDW 找不到分区 table

Postgres 11 FDW can't find partitioned table

正在尝试使用 postgres 11 外部数据包装器访问分区 table。我可以访问底层的 table,但不能访问 table。

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;

这好像没问题。然后我为此创建了一个 link:

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?

这是一个您应该报告的错误。

作为变通方法,您可以自己创建外部 table:

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');
