Replace PL/pgSQL functions with inlineable SQL functions

This speeds up the resolved_* views by a reasonable amount, though it
does mean we won't be able to use the smarter resolution logic (which is
far too slow anyway at the moment, so I'm not sure what I'm going to do
about that in the future...)
