YMMV.
+1 for this, I don't see it as a big deal, and I would hate to discover
there's some reason we care (I dunno, implicit casts from ARRAY to
hstore ?) in the future that we're not thinking about now.
This also means there's no ambiguity as to what the iterator variable
should be declared as- if you're doing a FOREACH .. ARRAY, then your
iterator is an ARRAY (if it's not a scalar, of course), full stop.
Thanks,
Stephen
