Hi all,
I am thinking about a HA solution using pgpool2 + postgresql streaming replication.
I am afraid of a split brain scenario (two active primary databases).
In my opinion a split brain scenario should never happen when
a) I configure the postgresql clusters (pg_hba.conf) to accept only user connections coming from the pgpool2 server
b) pgpool2 initiates the failover
Do you agree or did I miss something?
Thanks,
Markus
