I see that the second patch (0002) brings complexity in the patch to
deal with following points: (a) The first complexity is if one of the
partitions is specified then how to compute the initial set of
relations to copy when pubviaroot is true. This is complex because we
need to exclude the partitions specified. (b) The other complexity is
combining Except list containing partitions and other publications
specifying partitions or partitioned tables both during replication
and probably during initial sync.

I think it will be better if for the first version, we allow only root
partitioned table to be specified in the Except Table list. This would
mean that if the user tries to attach that root partition table to
another root then we should give an error. If we go via this route, it
will be important to allow users to remove some tables from the Except
list, so we can provide Alter Publication <pub_name> Set Except Table
(table_names).

I think excluding specific partitions may also have some use cases but
adding additional complexity and maintenance effort is worth, if there
is a real field demand for such a feature.

Thoughts?
