Glad to hear that. Usogres was developed in Japan and pretty popular
ammong Japanese PostgreSQL community.
BTW, there is a commercial product called QueryMaster, which takes
similar approach to Usogres. It copies the input query and distribute
to multiple PostgreSQL servers. As long as one of a server is working,
users even do not notice some of them are failing.
