[Pgpool-committers] pgpool - pgpool-II: Fix online recovery to wait for failback done before

[User T-ishii]

Log Message:
-----------
Fix online recovery to wait for failback done before allowing to
accept connections from clients. It was supposed to work like this but
actually was not since the day 0 when online recovery was
born. Without the fix there could be potential data inconsistency
among DB nodes.
