We were using slony well before 2009 with read slaves to handle massive read loads. While muti-master setups are still pretty new in the PostgreSQL universe, there are some seups like Bucardo. Of course this paper doesn't mention whether or not they're referring to shared storage or separate storage, and what kind of loads would be expected. RedHat Cluster server can provide failover etc. There are several different options that pre-date this article. The fact that it then goes on the sing the praises of MySQL clusters as reliable and stable makes me question the whole article. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
