Perhaps could be interesting to look at cluster file system which
seems to have same problems and find solution about locking (i.eOpenGFS).

Found on google a clustered shared memory (openMosix project)

I would have the pgsql-hackers genius for do that :) . I think its the
only feature which force company to buy 50000$ Oracle licence ...
