Thanks for the new patch version!

I did not look closely to the code yet but did some testing and I've one remark
regarding plugin_filtered_bytes: It looks ok when a publication is doing rows
filtering but when I:

- create a table and use pg_logical_slot_get_changes with ('skip-empty-xacts', '0')
then I see plugin_sent_bytes increasing (which makes sense).

- create a table and use pg_logical_slot_get_changes with ('skip-empty-xacts', '1')
then I don't see plugin_sent_bytes increasing (which makes sense) but I also don't
see plugin_filtered_bytes increasing. I think that would make sense to also increase
plugin_filtered_bytes in this case (and for the other options that would skip
sending data). Thoughts?
