I felt that we should keep the behavior consistent for all the three
scenarios i.e. table/tables in schema/all tables publication.
Furthermore, we should account for the reverse scenario: if a
publication is present for a table, an error should be thrown if we
attempt to attach a partitioned table with a foreign table to the
published table.
I noticed these are handled in the patch that Shlok has provided at [1].
