[NOVICE] Old solutions for listing tables by tablespace broken in PG 10 forpartitions.

I have tried the solutions for listing tables in a tablespace here:

https://www.postgresql.org/message-id/FA6A2975AD158C4A850EE96CF41AB63B3ED9FA6F%40BL2PRD0103MB041.prod.exchangelabs.com

select relname from pg_class where reltablespace=(select oid from pg_tablespace where spcname='xyz');

and here:

https://stackoverflow.com/questions/4970966/how-can-i-tell-what-is-in-a-postgresql-tablespace

SELECT

  c.relname,

  t.spcname

FROM

  pg_class c

    JOIN pg_tablespace t ON c.reltablespace = t.oid

WHERE

  t.spcname = 'indexes_old';

I don’t see partitioned tables in the list.  How do I get a list of tables including partitions by tablespace?
