I have created two publications one on each PostgreSQL instance but on the same table. Then I subscribed to these publications from each instance. I didn't see an error in the logs of two instances but I can see replication works on one side i.e. uni-directional.
Does logical replication support bi-directional or not?
Thanks
No, you cannot use logical replication to replicate the same table in both directions. This would necessitate complicated conflict resolution, which PostgreSQL doesn't have at the moment.
