Erm, it's a namespace inside of which objects exist.  Sure, the
individual tables might be on different tablespaces, but the schema's
size is a direct aggregation of the objects which it contains.

The argument that it doesn't have a size is a bit like arguing that 'du'
should report the directory's size rather than the combined size of
everything in it.

I look forward to someone adding this, it'd be nice to have.
