Really?
FOR var IN SELECT UNNEST(arr) LOOP ... END LOOP
I mean, doing everything is sort of clunky in PL/pgsql, but this
doesn't seem particularly bad as PL/pgsql idioms go.
That tends to over-flatten if you have nested arrays and just want to iterate
over the top level. In that case you must use generate_subscripts().
for i in array_lower(myarray,1) .. array_upper(myarray,1) loop ...
works well
