May I ask some more complex? I want to use ONE multidimensial array - the "id", "bytes_in" and "bytes_out". By another words, I need an array, each element of which must contain 3 values: ttc_id, bytes_in, bytes_out. I think it can be done like this:
It's problem. You have to wait for 8.3 where composite types in arrays are supported, or simply use three array variables (or use plperl or plpython). Arrays in plpgsql can be slow, if you often update big arrays.
