[Pgpool-general] kind mismatch among backends. keeps changing between servers

[» Ruben Alves]

Hello, I had the same problem last week.
Maybe is because the two nodes are not exactly the same. Functions like 
pg_dump/pg_restore are not sufficient to make a perfect replication. You 
should try rsync  or tar.gz your postgresql folder and send it to the 
others nodes.
I also found an interesting point, the way postgresql is configured in 
node1 and node2 should be practically the same (in my case: 
/etc/postgresql/8.3/main/postgresql.conf)

Regards,

Ruben
