Hi
I tested a concept iteration over array in format [key1, value1, key2, value2, .. ] - what is nice, it works for [[key1,value1],[key2, value2], ...] too2015-01-16 22:35 GMT+01:00 Andrew Dunstan <andrew@dunslane.net>:

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.

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.
cheers
