I was reviewing the design of patch003, and I have a query. Do we need
to even start an apply worker and create replication slot when
subscription created is for 'sequences only'? IIUC, currently logical
replication apply worker is the one launching sequence-sync worker
whenever needed. I think it should be the launcher doing this job and
thus apply worker may even not be needed for current functionality of
sequence sync? Going forward when we implement incremental sync of
sequences, then we may have apply worker started but now it is not
needed.
thanks
