I've not read the patches yet. But while I was reading the code around
sync node detection, I thought that it might be good idea to treat the
node with priority as special. That is, if we find the active node with
the priority 1, we can immediately go out of the sync-node-detection-loop.
In many cases we can expect that the sync standby has the priority 1.
If yes, treating the priority 1 as special is good way to do, I think. Thought?
