There two possible transformations: row_to_array --> [[key1, value1],[key2, value2], ...] row_to_row_array --> [(key1, value1), (key2, value2), ... ] If we're going to go that route, I think it makes more sense to create an actual key/value type (ie: http://pgxn.org/dist/pair/doc/pair.html) and return an array of that. ok <http://BlueTreble.com>
I think we'd possibly be better off with simply returning a flat array, [key1, value1, ...]
Thats's what the hstore(text[]) and json_object(text[]) functions accept, along with the 2D variant, if we want a precedent.
