psql: Add information in \d+ about foreign partitions and child tables
\d+ is already able to show if a partition or a child table is "PARTITIONED" via its relkind, hence the addition of a keyword for "FOREIGN" in the relation description is basically free. Author: Ian Lawrence Barwick Reviewed-by: Tom Lane, Michael Paquier Discussion: https://postgr.es/m/CAB8KJ=iwzbEz2HR9EhNxQLVhMk2G_OYtQPJ9V=jWLadseggrOA@mail.gmail.com
