psql \dP: list partitioned tables and indexes
The new command lists partitioned relations (tables and/or indexes), possibly with their sizes, possibly including partitioned partitions; their parents (if not top-level); if indexes show the tables they belong to; and their descriptions. While there are various possible improvements to this, having it in this form is already a great improvement over not having any way to obtain this report.
