Well, no. I haven't coded on a beowolf system (and my Linux Journal with
a writeup on it has gone wandering :( but a beowolf must be a MIMD
system with (perhaps) a shared file system. So, we would need a
medium-grained or coarse-grained decomposition of the backend to
distribute a single session across a cluster.

However, what I proposed would allow a single database, or parts of a
single logical database, to reside on one host, with access from a
client hitting multiple hosts to find all the tables, so one could
distribute the load if several pieces or many databases were involved.
Doesn't need to be a beowolf, just a networked set of servers.
