[Pgpool-committers] pgpool - pgpool-II: Do not keep persistent connection to backends.

[User T-ishii]

Log Message:
-----------
Do not keep persistent connection to backends.
The connection may become bogus if a node down and then wake up
between replication delay checking period.
Restarting worker process is not feasible since there is a time lang
between backend down and restarting worker process.
