Huh? Why'd you remove it? I can't imagine it makes things
significantly simpler to omit that case, and even if you can't
think of uses for it, I can (taking jobs from a to-do queue for
instance).
BTW, it occurs to me to wonder whether we've picked a good choice
of syntax. I don't remember where the suggestion to use "RETURNING"
came from (did we borrow it from another DBMS?). But AFAICS this
syntax will require the introducing keyword to be a fully reserved
word, and since RETURNING is not listed as a reserved word in the
SQL spec, reserving it is arguably a spec violation.
The simplest alternative that comes to mind is to use RETURNS instead of
RETURNING; since RETURNS is listed as reserved, this doesn't violate
spec. OTOH we currently treat RETURNS as an unreserved keyword, and
we'd have to promote it to fully reserved. It could be argued that
"returns" is a more likely name for a table column than "returning";
if so we'd actually be more likely to break existing apps this way.
I don't have a strong feeling either way, but now is the time to
decide.

OK, but we need a final version soon.
