I have committed the worker.c refactoring patch.

"Add subscription support to replicate into partitioned tables" still 
has lacking test coverage.  Your changes in relation.c are not exercised 
at all because the partitioned table branch in apply_handle_update() is 
never taken.  This is critical and tricky code, so I would look for 
significant testing.

The code looks okay to me.  I would remove this code

+       memset(entry->attrmap->attnums, -1,
+              entry->attrmap->maplen * sizeof(AttrNumber));

because the entries are explicitly filled right after anyway, and 
filling the bytes with -1 has an unclear effect.  There is also 
seemingly some fishiness in this code around whether attribute numbers 
are zero- or one-based.  Perhaps this could be documented briefly. 
Maybe I'm misunderstanding something.
