Re: Configuration of django with master slave replication Postgres

Hi Soumitra,
In pgpool-II you can configure watchdog mode, so if one pgpool fails the
other node of pgpool gets the VIP so that no change is required on client
side.
Can you show you django dsn config once?
I'm assuming you can do same with pgpool, " Even for that reason in django
I have to configure dsn like that so that it can automatically switch to
other node if one node is not reachable." If you switch your dsn IPs and
ports with 2 of pgpool node(if one pgpool fails dsn will switch to other
pgpool node).

Happy to help :)
