I am not so sure whether we need this patch as the exact scenario
where it can help is not very clear to me and neither did anyone
explained.  I have raised this concern earlier as well [1].  The point
is that 'logical_decoding_work_mem' applies to the entire
ReorderBuffer in the publisher's side and how will a parameter from a
particular subscription help in that?
