PGDOCS - function pg_get_publication_tables is not documented?

Hi hackers,

While reviewing another thread [1] I could not find the function
'pg_get_publication_tables' described anywhere in the PG
documentation.

Should it be mentioned somewhere like the "System Catalog Information
Functions" table [2], or was this one deliberately omitted for some
reason?

Thanks.
