BTW, checking my notes about this issue, I notice a related question:
should attstattarget be inherited for the inherited columns when a child
table is created? Right now it's not, and it might be a bit ugly to
make it so.
In a lot of scenarios you wouldn't necessarily expect the parent and
child tables to have similar contents, so I'm not sure inheriting
attstattarget is appropriate anyway. Comments anyone?
