[pgpool-general: 2953] PGPool and Watchdog

Hello All,

I have a load balancer in front of a pair of pgpool nodes (3.3.1), in front
of a pair of PostgreSQL   nodes (9.3) which are configured as a streaming
pair. I am running on RHEL.

I am using another HA tool to manage the failover between the Postgres
nodes, and the load is spread between the pgpool nodes with inactive nodes
being taken out of the load balanced pool.

Do I need watchdog in this case? I have seen reports that pgpool still
synchronises useful information using this connection, but can't find what
this information is?

If I did use watchdog, which settings would I need in this limited case?

Also is there a pcp command which I can use to tell pgpool that a new node
is master, but not actually promote it (this would have happened already)?
Does pcp_promote_node do this when no promotion script is provided?

Thanks for the help.
