[Pgpool-general] How to auto reattach a node

[Erwan]

Hi there,

I have the following use case:
Sometimes I have little timeouts on my network and pgpool-II detaches 
the node which is no more reachable (the state is equal to 3).
I wonder if it was possible to reattach "auto-magically" this node when 
there is no more timeout?

I imagine the health check is a solution to do that but I have several 
tiny dumb questions about this check:
- how the check is done? Because we have to specify a user but no 
password... I imagine I also have to change the pg_hba.conf file
- does it allow pgpool-II to reattach a detached backend?

Thanks in advance!
Cheers,
