I've read this Peter's post:
http://petereisentraut.blogspot.com/2010/04/news-from-sql-standard.html
which says in SQL2011 has a new feature:
> Combined data change and retrieval. PostgreSQL does something like this with RETURNING, but this feature is more elaborate and allows the writing of "delta tables".
And I heard from sources that this "delta table" contains something
like writeable CTEs. Couldn't you share something about it if
possible? I just don't like to design something that will be similar
to but different from the standard.
