I have to agree with you. This is not for 1.8. Your idea of maitaining a
list of dependent objects is good but too expensive. Another idea is to
query the pg_depend to get all the dependencies (imitating the DROP ...
CASCADE code) before drop the target object. So we could scan the tree
for these dependencies and remove them too.
