I'm just skimming through the changes and happened to spot two minor
things.

In 0008:

        if (pq_mq_handle != NULL)
+       {
            shm_mq_detach(pq_mq_handle);
+           pfree(pq_mq_handle);
+       }
        pq_mq_handle = NULL;

Maybe we could move "pq_mq_handle = NULL;" inside the if branch?
Though I see we're doing it in your way on master.

In 0015:

I noticed that we're freeing the list returned from
logicalrep_workers_find().  Should we do the same for the "workers"
list in AtEOXact_LogicalRepWorkers()?


This is very useful work; I hope we can get it in soon.

Thanks
