pgpool2 HA + split brain

От

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
