'replication_mode = true' means sincronous replication with pgpool-II, pgpool_walrecrunning function is used for streaming replication, configuring pgpool-II in master/slave sub-mode stream.

Thanks Tatsuo. By streaming replication mode, you mean the 'replication_mode = true' in pgpool.conf? If I use pgpool-II-3.0.3, and configure it in Master/Slave mode with sub mode as 'stream', then I do not need this function., right?

In pgpool-II 3.1 the function is not used anymore even in streaming replication mode. -- Tatsuo Ishii SRA OSS, Inc.
