I think we should at least display "Type" as "partitioned table" for a
partitioned table, so that it's easy to understand why the size is 0;
partitioned tables do not hold any data by themselves.

should be.

Some is missing still - there is not any total size across all partitions.

maybe new command like

\dtP+ .. show partitioned tables and their size
