title: Does logical replication supports bidirectional?
body: <p>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.</p>
  <p>Does logical replication support bi-directional or not?</p>
  <p>Thanks</p>
