High Availability, Load Balancing, and Replication Feature Matrix

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.
