Milla's syntax doesn't show that Oracle allows column level triggers.
That's the only difference I've noted. Column triggers are nice for
efficiency, e.g. the trigger doesn't fire when a column doesn't change. If
the trigger body is complex, you can test whether the OLD.col != NEW.col
for added efficiency in Postgres.

Currently no. There's no real need for it so there's not really a push
for it either.

Has had these for ages.

You can create RULEs to do this.

What would they do?

I'm not seeing anything there more than syntactic sugar that PostgreSQL
doesn't support, but no, it doesn't take that syntax.

Hope this helps,
