I believe Postgres is just following standards.
Yes, deferred is very useful for other things, like a real data model layer
mediating between UI and database--without it you have to worry about
performing inserts (and updates) in a particular order. That can be really
painful to code, and in some cases (cyclic relationships) impossible to do
except by leaving some constraints out.
