The patch looks good to me too in that it gets the job done.
Reading Alvaro's email at the top again gave me a pause to reconsider
what I had said in reply. It might indeed have been nice if the
publication DDL itself had prevented the cases where a partition and
its ancestor are added to a publication, though as Hou-san mentioned,
partition ATTACHes make that a bit tricky to enforce at all times,
though of course not impossible. Maybe it's okay to just de-duplicate
pg_publication_tables output as the patch does, even though it may
appear to be a band-aid solution if we one considers Alvaro's point
about consistency. Sorry about too many second thoughts on these
threads. :(

+1 to do this only in HEAD.
Thank you.
