I was going to post a question about the above bullet point(s), so this
clarification helps -- thanks!
Two comments on the above:
1. I do believe ther eis a missing "Tomas" in the first release note.
2. Would you want to s/standbys/subscribers/ given an instance can be in
read/write mode but still receive logical changes? Or did this patch
affect only subscribers that are also standbys?
Thanks,
Jonathan
