[pgpool-general: 5025] Re: Failover command not invoked by secondary pgpool after its promotion to primary in HA

[Christophe Le Roux]

Hi Tatsuo,

I guess higher default value could be better, because there is less drawback to have a high value than a low value for this parameter.

Regards,

Christophe

Christophe,

Thank you for studying it. Do you think it's a good idea to change the default value of search_primary_node_timeout to say, 300 in the pgpool.conf sample files?

Best regards,
