Thanks, Vignesh. Your suggestion (to move that "Subscribers" section)
seemed like a good idea to me, so PSA my patch v2 to implement that.
Now, on the Streaming Replication page
- the blurb has a reference to information about logical replication config
- the "Subscribers" section was relocated to the other page
Now, on the Logical Replication "Configuration Settings" page
- there are new subsections for "Publishers", "Subscribers" (copied), "Notes"
- some wording is rearranged but the content is basically the same as before
