A.21. Release 4.3.1

Suppress message length log for in_hot_standby. (Tatsuo Ishii)

PostgreSQL 14 introduced new config parameter in_hot_standby.

The value is either "on" for standby servers or "off" for primary servers. As a result pgpool log is flooded by the messages:

     LOG:  reading message length
     DETAIL:  message length (22) in slot 1 does not match with slot 0(23)
    

To avoid this, only complain if the parameter name is not in_hot_standby.

Also the message is enhanced to show the parameter name.

     LOG:  ParameterStatus "TimeZone": node 1 message length 30 is different from main node message length 24

Fix failover() to deal with the case when no former primary node exists. (Tatsuo Ishii)
