Mariposa (http://mariposa.CS.Berkeley.EDU/download.html) has a BSD licence
but it refers to Postgres95.
Mariposa is a patch aganist postgres sources and alpha release, there are a
lot of Papers describing this.
I've compiled under linux but no success.
It's possible that there isn't a solution or a trick to load-balance
postgres (at least cpu load balancing with a central high speed location for
data-bases) ?
thank you for your reply.
