Bug reference: 17055
Logged by: Sergey Bernikov
Email address: sbernikov@gmail.com
PostgreSQL version: 13.3
Operating system: Ubuntu 18.04.4
Description:
This error happens when logical replication target is partitioned table.
Steps to reproduce:
1. in source DB: create table and add to publication
create table test_replication (
id int not null,
value varchar(100),
primary key (id)
);
create publication test_publication for table test_replication;
2. in target DB: create partitioned table and start replication
create table test_replication (
id int not null,
value varchar(100),
primary key (id)
) partition by range (id);
create table test_replication_p_1 partition of test_replication
for values from (0) to (10);
create table test_replication_p_2 partition of test_replication
for values from (10) to (20);
create subscription test_subscription CONNECTION '...' publication
test_publication;
3. in source DB: insert data
insert into test_replication(id, value) values (1, 'a1');
4. in target DB: delete data
delete from test_replication where id = 1;
5. in source DB: update data
update test_replication set value = 'a2' where id = 1;
Result: logical replication worker on target server crashes with different
