Um, raise $150,000 to pay for a clustering implementation?

Various techniques of "shared memory clustering" have been tried with 
PostgreSQL, and none work.    Neither does LinuxLabs "ClusGres", which is 
based on similar principles -- unfortunately. (at least, LL repeatedly 
postponed the demo they said they'd give me.  I've yet to see anything 
working ...)

Frankly, we're waiting for a well-funded corporation to jump in and decide 
they want PostgreSQL clustering.   Database server clustering is a "big 
ticket item" requiring roughly 1,000 hours of programming and 
troubleshooting.   As such, you're not likely to see it come out of the OSS 
community unaided.

Oh, and FYI, MySQL's "clustering" doesn't work either.  It requires your 
entire database to fit into available RAM ....
