This point has not been discussed, so thanks for raising it. I think
the reasoning behind keeping it in logical is that this file contains
a code for logical slot syncing and a worker doing that. As it is
mostly about logical slot syncing so there is an argument to keep it
under logical. In the future, we may need to extend this functionality
to have a per-db slot sync worker as well in which case it will
probably be again somewhat related to logical slots. Having said that,
there is an argument to keep it under replication as well because the
functionality it provides is for physical standbys.
