In the table no bull mark is in "No conflict resolution necessary" row for pgpool-II. Actually this is wrong. Pgpool-II does not need conflict resolution.
Also in the same page "Pgpool-II has this capability." (here "this" means "Multiple-Server Parallel Query Execution") This used to be true long time ago but current stable versions of Pgpool-II do not support this any more. Attached patch fixes these.
