The way forward with updatable views is triggers on views. I was going

In the mentioned discussion there was already the notion of "substitution
rules". The notion of this pretty much applies to something like "instead
of statement triggers". AFAIR, the discussion came up with a proposal for
some CURRENT OF-Syntax in rules, which creates some magic rule effectively
avoiding the self join and substitute the original query with the
WHERE-condition of the view appended.
