Hi @all,
A question, found in the german PG-Forum:
is it possible to partitionate a lookup-table? What i mean is:
test=# create table foo(i int primary key);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "foo_pkey" for table "foo"
CREATE TABLE
test=*# create table bla ( i int references foo);
CREATE TABLE
test=*# insert into foo values (1);
INSERT 0 1
test=*# insert into bla values (1);
INSERT 0 1
test=*# create table foo_2 () inherits (foo);
CREATE TABLE
test=*# alter table foo_2 add primary key (i);
NOTICE: ALTER TABLE / ADD PRIMARY KEY will create implicit index "foo_2_pkey" for table "foo_2"
ALTER TABLE
Well, now i'd like to move data from foo into foo_2:
test=*# insert into foo_2 select * from foo;
INSERT 0 1
test=*# delete from foo;
ERROR: update or delete on table "foo" violates foreign key constraint "bla_i_fkey" on table "bla"
DETAIL: Key (i)=(1) is still referenced from table "bla".
Can i do that in an other way, or is it impossible? I think, it's
impossible, right?
