Agreed. > I've attached updated patches, please review it. It looks good to me, just one minor thing in 002: @@ -183,8 +184,10 @@ typedef struct Counters int64 local_blks_written; /* # of local disk blocks written */ int64 temp_blks_read; /* # of temp blocks read */ int64 temp_blks_written; /* # of temp blocks written */ - double blk_read_time; /* time spent reading, in msec */ - double blk_write_time; /* time spent writing, in msec */ + double blk_read_time; /* time spent reading blocks, in msec */ + double blk_write_time; /* time spent writing blocks, in msec */ + double temp_blk_read_time; /* time spent reading temp blocks, in msec */ + double temp_blk_write_time; /* time spent writing temp blocks, in msec */ maybe the comments should respectively be data file blocks and temp file blocks. This is a minor detail and the rest of the patch looks good to me, so I'm marking the patch as Ready for Committer!
