## A.153.1. Bug fixes

- Fix incorrect query rewrite in replication mode. (Bo Peng)

- Fix that health check timeout does work in certain case. (Tatsuo Ishii)

  Discussion: [pgpool-hackers: 3458], [pgpool-hackers: 3459]

- Doc: add failover_command description when all standby nodes are down. (Takuma Hoshiai)

- Doc: add note not to assign PostgreSQL servers to trusted_servers. (Tatsuo Ishii)

- Fix for miscellaneous watchdog issues. (Muhammad Usama)

  The lost nodes reported by life-check are treated as hard failures even when the node is reachable from the watchdog core.

  In the case of network partitioning or partial life-check failure, the kicked out standby node was too aggressive in trying to connect to the master or become a master itself so that potentially put the unnecessary burden on the network and the cluster nodes. Fix is to make the isolated node a bit calm and wait between trying to connect to master or become a master.
