Slow, complicated to code, and deadlock-prone (since you'd have to
acquire locks on the other parent tables). My feeling is we fix this
with a counted attisinherited field, or don't fix at all.
We can certainly do the proper fix in 7.4; do we consider this bug
important enough to do an initdb for 7.3beta2? I don't have a strong
feeling either way about that.
