Postgres arrays question


Does anyone know whether there is any nice way of dealing with data that is stored in postgres tables in array fields?
When I issue query:

I obtain result:

{{93.0,1},{118.7,2},{127.2,3},{139.6,4},{141.7,5}} ... and so on.
My question is how to access this date in ROOT (without writing own parser)?
Of course I could have issued query like that:

But is there any simpler way?



Finally, having no better ideas I decided to use istringstream and it worked.
