Yes, which begs the question of why bother at all.  AFAICS this patch
simply allows you to replace
for x in select unnest(array_value) loop

with
for x in unnest array_value loop

(plus or minus a parenthesis or so).  I do not think we need to add a
bunch of code and create even more syntactic ambiguity (FOR loops are
already on the hairy edge of unparsability) to save people from writing
"select".
