Hi everyone,
Im just testing/learning how subscriptions and publications work, then this is what i have done until now:
Server A :
create database test_pubsubs;
create table foo(
id_foo serial not null primary key,
foo varchar(20) not null
);
insert into foo values(1,'foo');
insert into foo values(2,'foobar');
create table foobar(
id_foobar serial not null primary key,
foobar varchar(20) not null
);
insert into foobar values(1,'foobaz');
insert into foobar values(2,'foobax');
create publication my_publication for table foo;
Server B :
create database test_pubsubs;
create table foo(
id_foo serial not null primary key,
foo varchar(20) not null
);
create table foobar(
id_foobar serial not null primary key,
foobar varchar(20) not null
);
select * from foo;
id_foo | foo
1 | foo
2 | foobar
select * from foobar;
0 Rows
Server A:
alter publication my_publication add table foobar;
Server B:
alter subscription my_subscription refresh publication;
select * from foobar;
id_foobar | foobar
1 | foobaz
2 | foobax
Then, here's my question :
Still on Server B:
delete from foo;
delete from foobar;
select * from foo;
0 Rows
select * from foobar;
0 Rows
alter subscription my_subscription refresh publication;
select * from foo;
0 Rows
select * from foobar;
0 Rows
Why ? If i remove rows, from Server B and refresh publication, why data is not re-sync ?
But if i :
drop subscription my_subscription;
and create it again, then i have all data back...
Thanks a lot!
