It's just the overall getrusage result for the backend process. > what I don't know and never found so far is "Local blocks" and "Direct > blocks". So I'd be interested to know what's this, jst for completeness. Local blocks are (or were ... that code is gone as of 9.0) I/O for temporary tables of the current backend.
