Some of this is getting solved by making PostgreSQL more pluggable in ways that isolate the proprietary stuff, i.e. make people not have to touch the PostgreSQL core code much, if at all, in order to provide whatever special features they provide. Hooks and FDWs are two such pluggable components.
Extensions and the lovely background workers as well.
