I had a look at the page and could not see the reference, so this
suggestion may be inappropriate, but...

How about something more general - an incredibly useful feature of Dec/Rdb is:

    insert into t1(...) values(...) returning attr-list

which is like performing a select directly after the insert. The same kind
of syntax applies to updates as well, eg.

    update t1 set f1 = 2 where <stuff> returning f1, f2, f3;

Perhaps your original suggestion is a lot easier, but this is a convenient
feature...
