Re: Declarative partitioning - another take

Hi ,

I tried "COPY FROM" in the git version. It inserts rows to wrong partition.

step to reproduce:
create table t(a int, b int) partition by range(a);
create table t_p1 partition of t for values from (1) to (100);
create table t_p2 partition of t for values from (100) to (200);
create table t_p3 partition of t for values from (200) to (300);
insert into t values(1,1);
insert into t values(101,101);
insert into t values(201,201);
copy (select * from t) to '/tmp/test2.txt';
copy t from '/tmp/test2.txt';
select * from t_p1;

result:
postgres=# select * from t_p1;
a | b
-----+-----
1 | 1
1 | 1
101 | 101
201 | 201
(4 rows)

I think the argument "BulkInsertState" used in CopyFrom/heap_insert
is related to this problem. Please check it.

Thanks.
