Streaming replication info

Hi there,
I would to configure a multinode PostgreSQL system using streaming
replication. In my mind, I would have a base configuration with a master
node and more than one slaves in streaming replication.

I have no difficult to imagine start situation, but my problems come when
master fails: if my slaves receive strems from the master, when this fails
is there a manner to change connection_info in recovery.conf and change
server to a new master?

Is there a manner to reload recovery.conf without restart nodes?

Or the only solution of this situation is that all slaves became "masters"?

Thanks in advance.

Regards

Meph

Cool.

I suggest that you look at repmgr, an open-source tool for managing
replication the we are currently writing
(http://projects.2ndquadrant.com/repmgr) which should make this kind of
things much easier for you.

Cheers,
Gabriele
