pg_class doesn't show inheritance. I *think* all you'd have to do is
insert rows into pg_inherits, see

http://developer.postgresql.org/docs/postgres/catalog-pg-inherits.html

Oh, and you'd have to set pg_class.relhassubclass true for the parent
table.

But I've not tried to do this by hand myself. Better experiment on
a test database ;-)
