Email address: mr(dot)kaleek(at)gmail(dot)com
PostgreSQL version: 12.1
Operating system: Ubuntu 16.04.6 LTS
Description:

I got error when replicate with native logical method from PostgreSQL 11.6
to PostgreSQL 12.1, I will connecting table partition to table partition
from Version 11.6 to Version 12.1, but after all tables already replicated
around more than 2 hours, server can't access and recovery mode.

Actually we are facing problem when replicating partition table from 11.6 to
12.1, but if there is no partition table the replication works so well.
As FYI, our server spec is 16 core and 64GB. And we are using this ubuntu

LSB Version:
core-9.20160110ubuntu0.2-amd64:core-9.20160110ubuntu0.2-noarch:security-9.20160110ubuntu0.2-amd64:security-9.20160110ubuntu0.2-noarch
Distributor ID: Ubuntu
Description: Ubuntu 16.04.6 LTS
Release: 16.04
Codename: xenial
