postgresql11: How to use publication/subscription on primary/standby setup

[Abhishek B <abhishekbhola05@xxxxxxxxx>]

Is there a solution to use publication/subscription on a master-slave or primary-standby postgres setup without manual intervention?

Currently the DB clusters are managed by Pacemaker. Once there is a failover, the pacemaker is able to promote the secondary node to primary, but the logical replication stops working after that. Is there any way to automatically move the contents of pg_replslot to the new primary node? 

Thanks and regards,
