Bugs go to pgsql-bugs, how I don't think this is really a bug, but
a "feature".

Postgres has a feature where tables not listed in FROM clauses get silently
included. There is something that turns this off, but I think it is
only available in the development version. This feature is really only
useful for delete where there isn't a syntax to specify addition tables
and you need to use a subquery instead. A number of people didn't like the
way it works now as that usually when you end up using this feature
it is a mistake in the query rather than intentional use.
