Hi Petr,

Do I understand correctly that this depends on the "logical decoding
on standby" patch, but that isn't in the Commitfest? Seems like an
oversight, since that thread has a recently posted v11 patch that
applies OK, and there was recent review. You patches no longer apply
on top though. Would it make sense to post a patch set here including
logical-decoding-on-standby_v11.patch + your two patches (rebased),
since this is currently marked as "Needs review"?
